Geometrically nonlinear and coupled thermopiezomechanical modeling and analysis of smart FGM plates and shells


Abstract eng:
This paper deals with the nonlinear piezothermoelastic modeling and analysis of smart piezolaminated Functionally Graded Material (FGM) structures. A finite element concept based on the weak formulations of the field equations is considered and a 2D-shell element in the framework of Reissner-Mindlin (FOSD) theory is developed to deal with thin-walled FGM shell structures. The fully geometrically nonlinear shell theory accounts for small strains and large rotations, as well as for the nonlinear coupling effects in thermopiezoelastic continua. Three numerical examples are studied in this paper, a hinged FGM shell to analyze the pre- and post-buckling paths, a FGM plate strip under axial compression to highlight the nonlinear thermoelastic effects, and a multi-layered piezo plate to focus on the piezothermoelastic coupling phenomenon.
