Instructions for Authors

1. General Information

Thank you for considering the Uzbek Journal "Problems of Mechanics" for the publication of your research.

The journal publishes original and scientifically significant research in theoretical and applied mechanics, solid and fluid mechanics, computational mechanics, structural engineering, mechanical engineering, transport systems, machinery, materials engineering, and related disciplines.

The journal accepts manuscripts in English, Russian, and Uzbek. Authors are responsible for the accuracy, clarity, grammar, terminology, and overall quality of the submitted text.

Authors must follow these instructions and use the current official manuscript template. Manuscripts that do not meet the journal’s technical, scientific, ethical, or formatting requirements may be returned for correction before editorial assessment or peer review.

2. Manuscript Types and Article-Type Requirements

The journal accepts the manuscript types listed below. The Editorial Office may consider another type only when its purpose, structure, and relevance to the journal’s scope are clearly justified.

The journal does not impose one universal word limit for every manuscript type. Authors should use the length required to report the work clearly, transparently, and without unnecessary repetition. The Editorial Office may request shortening or restructuring where appropriate.

Authors must follow any reporting guideline relevant to the study design. Where a formal checklist applies, it should be submitted as a supplementary file.

 

3. Originality and Exclusive Submission

The submitted manuscript must be original, must not have been published previously in substantially the same form, and must not be under consideration by another journal.

The manuscript must not contain plagiarism, inappropriate text recycling, fabricated or falsified data, misleading image manipulation, duplicate or redundant publication, citation manipulation, or other research misconduct.

Posting a manuscript as a preprint does not normally prevent submission. Authors must disclose any existing preprint and provide its link or persistent identifier during submission.

4. Online Submission

All manuscripts must be submitted through the journal’s online submission system. A submission sent only by email is not considered formally submitted unless the Editorial Office specifically requests that method.

The submitting author is normally the Corresponding Author and is responsible for completing all submission steps, entering complete and accurate metadata, including all eligible co-authors, confirming that all authors approved the submitted version, and communicating with the journal during peer review, revision, production, and post-publication stages.

Before completing the submission, authors must review and confirm the journal’s Submission Checklist.

5. Submission Metadata

The following metadata must be entered completely and accurately in the online submission system:

·         manuscript title, abstract, keywords, language, and manuscript type;

·         full names of all authors in the correct order;

·         department, institution, city, postal code, and country for each affiliation;

·         email address and ORCID identifier for each author, where available;

·         identification of the Corresponding Author;

·         funding information and the role of the funder or sponsor;

·         conflicts of interest;

·         ethics approval and consent information, where applicable;

·         Data Availability Statement;

·         Artificial Intelligence Disclosure, where applicable.

6. Files Required for Submission

Title Page

The Title Page must include:

·         manuscript type and full manuscript title;

·         full names of all authors;

·         department and institution names;

·         city, postal code, and country for each affiliation;

·         email address of each author;

Anonymous Manuscript

The file submitted for double-anonymous peer review must not contain:

·         author names, affiliations, email addresses, or ORCID identifiers;

·         acknowledgements identifying individuals or institutions;

·         file properties or hidden metadata that could identify the authors.

Authors should use neutral wording when referring to their own previous work where necessary, without removing essential citations.

Where revision is requested, authors must submit:

·         a clean revised manuscript;

·         a marked or tracked-changes version, where requested;

·         a detailed point-by-point response to reviewers;

·         updated supplementary files, where applicable.

7. Accepted File Formats

Microsoft Word

Word manuscripts must be prepared using the current official Microsoft Word template and submitted as one editable .docx file. Figures and tables should be inserted close to their first citation in the manuscript. The Editorial Office may request separate original figure files.

LaTeX/Overleaf

Authors using LaTeX must use the official LaTeX/Overleaf package made available by the journal. All source files must be supplied in one ZIP archive, including the main .tex file, bibliography files, required class and style files, figures, supplementary source files, and a compiled PDF. The Editorial Office must be able to recompile the submission.

General File Requirements

Files should use common, accessible, and non-proprietary formats wherever possible. File names should be clear, brief, and free from confidential author information in files intended for anonymous review. Executable or potentially unsafe files must not be submitted unless specifically requested and securely handled by the Editorial Office.

8. Double-Anonymous Peer Review

The journal uses a double-anonymous peer-review process. Reviewers do not receive the identities of authors, and authors do not receive the identities of reviewers.

Authors must ensure that the anonymous manuscript does not reveal their identity. A publicly available preprint may make the authors’ identities discoverable; therefore, complete anonymity cannot be guaranteed where a manuscript has previously been posted as a preprint.

Research manuscripts are normally evaluated by at least two independent reviewers. The final decision is made by an authorized editor on the basis of scientific quality, reviewer reports, relevance, originality, methodological reliability, and compliance with journal policies.

9. General Manuscript Preparation

The manuscript must follow the official template and should use a single-column format during initial submission unless the template provides otherwise.

·         write clearly and consistently;

·         use numbered headings and subheadings where appropriate;

·         use editable text rather than images of text;

·         define specialist terms, symbols, and abbreviations;

·         avoid unnecessary repetition;

·         use automatic equation, figure, table, and reference numbering where possible;

·         ensure that the title, abstract, keywords, main text, declarations, figures, tables, equations, and references are complete at submission.

10. Title

The title must be concise, informative, specific, relevant to the manuscript, and representative of its principal subject and contribution. Avoid unnecessary abbreviations, formulas, uncommon symbols, and overly general expressions.

11. Authors and Affiliations

Authors’ names must be written in their full and consistent form. Each affiliation must use the following order: Department, Institution, City, Postal Code, Country.

At least one author must be identified as the Corresponding Author. Valid ORCID identifiers should be provided where available. The spelling of names in the manuscript, submission metadata, ORCID records, and previous publications should be consistent.

Changes to authorship after submission require a written explanation and the agreement of all affected authors. Changes after acceptance are permitted only in exceptional and justified circumstances.

12. Abstract

The abstract must be presented as one paragraph, must not exceed 200 words, and must accurately reflect the manuscript. It should not contain references unless absolutely necessary, undefined abbreviations, unsupported claims, or information not reported in the manuscript.

For Research Articles, the abstract should contain the following elements within one continuous paragraph: Background, Methods, Results, and Conclusions. Separate subheadings inside the abstract are not required.

13. Keywords

Authors must provide three to ten keywords. Keywords should accurately represent the manuscript, use recognized disciplinary terminology, avoid repeating the complete manuscript title, avoid very broad or unclear terms, and support indexing and discoverability.

35. Author Declaration and Submission Confirmation

By completing the submission, the Corresponding Author confirms that:

·         the manuscript is original and is not under consideration by another journal;

·         all listed authors meet the journal’s authorship criteria;

·         all authors have approved the manuscript, author order, declarations, and submission metadata;

·         all relevant funding, competing interests, ethics, consent, data availability, and AI-use information has been disclosed;

·         permission has been obtained for third-party material;

·         the authors understand the journal’s copyright, licence, Open Access, and publication-fee conditions;

·         the authors will cooperate in correction, investigation, or post-publication action where necessary.

Confirmation Mechanism

The journal may record this confirmation through mandatory online checkboxes, a timestamped electronic declaration, a signed form, or another documented electronic mechanism. A separate paper signature is not required unless specifically requested.

36. Copyright and Licence

Authors retain copyright to their articles and are not required to transfer copyright to the journal or publisher. By accepting publication, authors grant the journal and publisher a non-exclusive right of first publication and the rights necessary to distribute, archive, index, preserve, and maintain the article and its metadata.

Accepted articles are published under the Creative Commons Attribution 4.0 International Licence (CC BY 4.0). This licence permits copying, sharing, adaptation, and commercial or non-commercial reuse provided that appropriate credit is given to the authors, the original publication is identified, a link to the licence is supplied, and changes are indicated.

Authors are responsible for obtaining permission to use third-party material not covered by the article’s licence. See the journal’s Copyright and Licensing Policy, Open Access Policy, and Repository Policy for full details.

37. Publication Fees

There is no manuscript submission fee and no separate peer-review fee. No payment is requested before the final acceptance decision.

The standard Article Processing Charge (APC) is USD 100 per accepted article. For articles accepted between 1 January and 31 December 2026, the APC is fully covered by the journal’s Founder. Authors of articles accepted during 2026 are therefore not required to pay a publication fee, no separate waiver application is required, and no APC invoice is issued to authors.

Payment, exemption, waiver, discount, or financial support does not influence peer review or the editorial decision. The APC is a charge for publication services and is not a payment for acceptance.

For subsequent years, the applicable APC and any waiver, discount, or financial-support arrangements will be announced transparently on the journal website before manuscript submission and before any payment is requested. No revised fee will be applied retroactively to an article already accepted under previously announced conditions.

The journal does not charge a manuscript-withdrawal fee. For articles accepted during 2026, no APC is collected from authors, so refund conditions are not applicable. In a future period when an APC is payable, duplicate or erroneous payments will be refunded, and a payment will be refunded if the journal is unable to proceed with publication after receiving it. An APC normally becomes non-refundable after substantive production has begun or the article has been published, except where the journal determines that an administrative or technical error justifies a refund.

See the journal’s Publication Fees (APC) Policy for the complete and current conditions.

38. Revision of Manuscripts

Where revision is requested, authors must submit a revised manuscript, a detailed point-by-point response to reviewers, a clear explanation of all changes, and a reasoned justification where a recommendation has not been followed.

Changes should be marked using tracked changes, highlighting, or another method requested by the editor. A clean version must also be submitted where requested. Submission of a revision does not guarantee acceptance.

39. Proofs and Final Publication

After acceptance, the manuscript may undergo technical editing, copyediting, formatting, typesetting, metadata verification, reference checking, and preparation of the final PDF and online version.

The Corresponding Author will receive proofs for final checking. At the proof stage, authors should correct production errors, factual errors, and minor essential issues only. Major changes to the title, authorship, data, methods, results, or conclusions are not normally permitted.

Proofs must be returned within the period specified by the Editorial Office. The Corresponding Author confirms that all authors have approved the final version for publication.

40. Corrections and Post-Publication Responsibilities

Authors must promptly inform the Editorial Office if they identify a significant error, omission, or ethical concern after publication and must cooperate with any necessary investigation or corrective action.

The journal may publish a correction, Expression of Concern, retraction, withdrawal notice, or another update in accordance with its Corrections, Retractions and Post-Publication Updates Policy.

41. Privacy

Names, email addresses, affiliations, ORCID identifiers, and other information entered into the journal system will be used for editorial, peer-review, publishing, indexing, DOI registration, archiving, preservation, and related scholarly communication purposes.

Personal data will be processed in accordance with the journal’s Privacy Statement.
