Modeling and Simulation of FGPM Cantilever Beam Under Quadratic Thermal Gradient Distribution
Compared with composite materials, functionally graded materials can provide better specific stiffness and reduce the risk of delamination damage. Functionally graded piezoelectric material (FGPM) is an extraordinary functional graded material coupled with elastic and electric fields. To calculate the mechanical response of the piezoelectric gradient structure under quadratic distribution of thermal gradient accurately, a thermo-electro-elastic coupled simulation for piezoelectric gradient structure under nonlinear thermal field is proposed based on the FOSD hypothesis. The influences of material distribution, thickness and aspect ratio on the deformation of the structure under the nonlinear thermal gradients are obtained by parameteric investigation. The mechanical response results demonstrate that the numerical computation accuracy improves efficiently by considering the thermal distribution effect on FGPM.
