Vibration characteristics of a sandwich plate with viscoelastic auxetic core and graphene nanoplatelets reinforced skins
The present research aims to examine the free vibrational behavior of a sandwich plate comprising a viscoelastic auxetic core and functionally graded graphene nanoplatelets reinforced composite (FG-GPLRC) face layers, which are rested on a Winkler–Pasternak foundation. The macro-mechanical characteristics of the plate’s skins have been determined utilizing the Halpin–Tsai theory. Additionally, for the core layer, besides the features characterized using Gibson’s model, the Zener model is employed to describe its viscoelastic behavior. The equations of motion for the sandwich plate were derived based on Reddy’s third-order shear deformation theory (TSDT), and they were solved using the Galerkin method. To validate the numerical results of the current study, they have been compared with findings documented in prior ones. Overall, the effects of several parameters such as geometrical parameters, various GPL distribution patterns, boundary conditions, Winkler–Pasternak coefficients, and the volume fractions of GPL have been investigated on the natural frequency and loss factor of the sandwich plate.
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.
