Abstract

In this study, a general visco-Winkler–Pasternak foundation will be created to analyze the vibrations of functionally graded sandwich plates. The visco-Winkler–Pasternak foundations serve as the base for the suggested viscoelastic foundation, which takes into account a new damping coefficient related to the shear layer’s shear interactions. The new viscoelastic foundation model can be easily reduced to other well-known visco- and elastic foundation models. Establishing the governing equations of motion is achieved using the simple higher-order shear deformation theory and Hamilton's principle. Applying analytical solutions to these equations involves solving them with different boundary conditions. The proposed model is validated through some comparison studies. To demonstrate the effects of certain parameters on the vibration behaviors of functionally graded sandwich plates resting on general visco-Winkler–Pasternak foundations, a parametric study is performed. The numerical results section presents some novel findings and emphasizes the importance of two damping coefficients on plate vibration behaviors.

期刊介绍： Archives of Civil and Mechanical Engineering (ACME) publishes both theoretical and experimental original research articles which explore or exploit new ideas and techniques in three main areas: structural engineering, mechanics of materials and materials science. The aim of the journal is to advance science related to structural engineering focusing on structures, machines and mechanical systems. The journal also promotes advancement in the area of mechanics of materials, by publishing most recent findings in elasticity, plasticity, rheology, fatigue and fracture mechanics. The third area the journal is concentrating on is materials science, with emphasis on metals, composites, etc., their structures and properties as well as methods of evaluation. In addition to research papers, the Editorial Board welcomes state-of-the-art reviews on specialized topics. All such articles have to be sent to the Editor-in-Chief before submission for pre-submission review process. Only articles approved by the Editor-in-Chief in pre-submission process can be submitted to the journal for further processing. Approval in pre-submission stage doesn''t guarantee acceptance for publication as all papers are subject to a regular referee procedure.
