Abstract

The present paper deals with the deflection and thermoelastic damping analysis of micro-scale microstretch, micropolar, generalized thermoelastic thin plate. The analytical expressions for the transverse vibrations of a homogeneous, isotropic, microstretch, micropolar, generalized thermoelastic thin plate, based on Kirchhoff theory have been derived. The axial ends of the plate are assumed to be at either clamped or simply supported conditions. Analytical results for deflection, microstretch functions, temperature distribution, thermoelastic damping and frequency shift have been obtained. The numerical simulation has been carried out with the help of MATLAB software for magnesium like material. The graphical representations and interpretations have been discussed for thermoelastic damping of plate under various boundary conditions and for distinct considered values of thickness and length as well.
