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.

Authors must carefully follow these instructions and use the journal’s official Microsoft Word or Overleaf 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.

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.

2. Manuscript Types

The journal accepts the following manuscript types:

  • Research Article — an original study presenting analytical, numerical, computational, theoretical, or experimental results;
  • Review Article — a critical and structured analysis of current knowledge in a defined research area;
  • Short Communication — a concise report of important preliminary or narrowly focused findings;
  • Technical Note — a description of a new method, model, device, technical solution, computational procedure, or improvement;
  • Case Study — a detailed analysis of a specific engineering, mechanical, industrial, structural, or technological case;
  • Perspective — an evidence-based discussion of emerging directions, challenges, or future developments;
  • Editorial — a contribution prepared or invited by the Editorial Office;
  • Letter — a concise scientific comment, response, or discussion relating to a published article or a relevant research issue.

The Editorial Office may consider other manuscript types where their content is relevant to the journal’s scope.

3. Originality and Exclusive Submission

The submitted manuscript must:

  • be original;
  • not have been previously published in substantially the same form;
  • not be under consideration by another journal;
  • not contain plagiarism, fabricated or falsified data, inappropriate image manipulation, duplicate publication, or citation manipulation.

Posting a manuscript as a preprint does not normally prevent its submission to the journal. 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.

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;
  • communicating with the journal during peer review, revision, production, and post-publication stages.

Submissions sent only by email are not considered formally submitted unless requested by the Editorial Office.

5. Files Required for Submission

Authors should prepare the following files:

Title Page

The Title Page must include:

  • manuscript type;
  • full manuscript title;
  • full names of all authors;
  • institutional affiliations;
  • department and institution names;
  • city, postal code, and country;
  • email address of each author;
  • ORCID identifier of each author, where available;
  • name and contact details of the corresponding author;
  • acknowledgements or other information that could identify the authors.

Anonymous Manuscript

The file submitted for peer review must not contain:

  • author names;
  • affiliations;
  • email addresses;
  • ORCID identifiers;
  • acknowledgements identifying individuals or institutions;
  • information in file properties that could identify the authors.

Authors should replace identifying references to their previous work with neutral wording where necessary without removing essential citations.

Supplementary Files

Where applicable, authors should submit:

  • original figure files;
  • supplementary tables;
  • datasets;
  • computer code;
  • multimedia files;
  • reporting checklists;
  • permission documents;
  • ethics or consent documents requested by the Editorial Office.

6. Accepted File Formats

Manuscripts must be prepared using the journal’s official Microsoft Word or Overleaf template.

Microsoft Word manuscripts

The manuscript should be submitted as one editable Word file. Figures and tables must also be inserted into the manuscript near their first citation.

Overleaf manuscripts

All source files must be compiled into one ZIP archive, including:

  • the main .tex file;
  • bibliography files;
  • class and style files where required;
  • figures and illustrations;
  • supplementary source files;
  • a compiled PDF version.

The Editorial Office must be able to recompile the submitted files.

Files should use common, accessible, and non-proprietary formats wherever possible.

7. Double-Anonymous Peer Review

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

Authors must ensure that the anonymous manuscript does not reveal their identity.

The availability of a public preprint may make the authors’ identities discoverable. Therefore, complete anonymity cannot be guaranteed where the manuscript was previously posted as a preprint.

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

8. General Manuscript Preparation

The manuscript should:

  • follow the official journal template;
  • use a single-column format during initial submission unless the template provides otherwise;
  • be written clearly and consistently;
  • use numbered headings and subheadings where appropriate;
  • use editable text rather than images of text;
  • define all specialist terms, symbols, and abbreviations;
  • avoid unnecessary repetition;
  • use automatic equation, figure, table, and reference numbering where possible.

The manuscript title, abstract, keywords, main text, declarations, figures, tables, equations, and references must be complete at submission.

9. Title

The title must be:

  • concise;
  • informative;
  • specific;
  • relevant to the manuscript;
  • representative of the principal subject and contribution.

Avoid unnecessary abbreviations, formulas, uncommon symbols, and overly general expressions in the title.

10. Authors and Affiliations

Authors’ names must be written in their full and consistent form.

Each affiliation must include:

Department, Institution, City, Postal Code, Country

At least one author must be identified as the corresponding author.

Authors should provide valid ORCID identifiers where available. The spelling of names in the manuscript, OJS metadata, ORCID records, and previous publications should be consistent.

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

11. Abstract

The abstract must:

Where revision is requested, authors must submit:

  • a revised manuscript;
  • a detailed point-by-point response to reviewers;
  • a clear explanation of all changes;
  • justification where a reviewer’s recommendation was not followed.

Changes should be clearly marked using tracked changes, highlighting, or another method requested by the editor.

Submission of a revision does not guarantee acceptance.

37. Proofs and Final Publication

After acceptance, the manuscript may undergo:

  • technical editing;
  • copyediting;
  • formatting;
  • typesetting;
  • metadata verification;
  • reference checking;
  • preparation of the final PDF and online version.

The corresponding author will receive proofs for final checking.

At the proof stage, authors should correct only production errors, factual errors, and minor essential issues. Major changes to the title, authorship, data, methods, results, or conclusions are not normally permitted.

Authors must return corrected proofs within the period specified by the Editorial Office.

38. Corrections and Post-Publication Responsibilities
