Abstract
The purpose of this study is to investigate the bending analysis of metal (Ti-6Al-4V) ceramic (ZrO_2) functionally graded material (FGM) sandwich plate having material property gradation along length and thickness direction under thermo-mechanical loading using inverse trigonometric shear deformation theory (ITSDT). Mechanical and thermal properties of BDFGM sandwich plates are considered temperature-dependent in the present study. Analytical solution for bending analysis of FGM plate has been carried out using Hamilton’s principle and Navier’s solution.
The present study shows that centre deflection, normal stress, and shear stress are significantly influenced by temperature-dependent material properties, bi-directional gradation exponents’ geometrical parameters, sandwich plate layer thickness, etc.
