Wave propagation analysis of a ceramic-metal functionally graded sandwich plate with different porosity distributions in a hygro-thermal environment

Wave propagation analysis of porous functionally graded (FG) sandwich plate in a hygro-thermal environment is presented in this paper. The sandwich plates’ composing materials change through three layers that are either homogeneous ceramic, homogeneous metal, or power-law-based functionally graded ceramic–metal. Six different porosity models are considered in the analysis to express the porosities’ distribution factor and uniformity. The study...
