Lord-Shulman based generalized thermoelasticity of piezoelectric layer using finite element method

F. Kheibari, Y. Tadi Beni and Y. Kiani

Abstract

In the present work generalized thermoelasticity of a piezoelectric layer is analysed under various shock loading conditions. The generalized thermoelasticity is based on the Lord-Shulman model. The governing equations are solved in the space domain using the finite element method and for solving the equations in the time domain the Newmark method is used. Two kinds of shock loading, temperature shock, and stress shock loading are considered. The results are compared with same results presented in other works and a very close agreement is observed. Finally, the results for each loading condition are presented in various locations and times.
