PEER REVIEW AND EDITORIAL POLICY
The journal follows the Springer Nature Peer Review Policy, Process and Guidance, Springer Nature Journal Editors' Code of Conduct, and COPE's Ethical Guidelines for Peer-reviewers.
Approximately 5% of the manuscripts are rejected without review based on formal criteria as they do not comply with the submission guidelines. Each manuscript is assigned to at least one peer reviewer. The journal follows a single-blind reviewing procedure. The period from submission to the first decision is up to 33 days. The approximate rejection rate is 10%. The final decision on the acceptance of a manuscript for publication is made by the meeting of the most active members of the Editorial Board.

Paimushin V.N., Firsov V.A., Shishkin V.M.
Abstract

The paper discusses the effectiveness of currently used methods of surface damping of bending vibrations for thin-walled structures. The special features of surface damping of vibrations using a free and constraining layer damping are analyzed from a physical point of view and practical application. A combined damping coating is proposed, which allows integrating the positive qualities of both of the above methods. An experimental comparison of the effectiveness of the known and proposed methods for damping of bending vibrations of thin-walled structures is made using the method of free damped oscillations.
