Guided wave propagation of porous functionally graded plates: The effect of thermal loadings

Because there is no literature on the effect of thermal loadings on guided wave propagation in FG plates, the present paper is to fill the gap. In the present paper, the wave propagation analysis of porous FG plates with clamped ends in thermal environments based on first order shear deformation theory are presented. The plates are exposed to various types of thermal loading including uniform and non-uniform temperature changes, the material properties of FG plates are temperature- and porosity-dependent. Using the Galerkin method, we obtain the dispersion relation of thermoelastic waves in porous functionally graded plates. Compared with the previous results, the correctness of the present work is verified. In the end, the effects of the temperature changes, porosity as well as power law index on the phase velocity and group velocity of the guided wave are investigated.

Automated summary

This paper investigates the wave propagation in porous FG plates in thermal environments, examining the effects of various thermal loadings on material properties and the influence of temperature changes, porosity, and power law index on the phase velocity and group velocity of guided waves.
