摘要：

The response of composite plates constructed of graphite/epoxy laminae with an attached piezoelectric polyvinylidene fluoride layer subjected to mechanical, thermal and electric field loading is considered for various length-to-depth and aspect ratios. First-order shear deformation theory is extended to include the piezothermoelastic response of composite plate structures. Analytic results are obtained for a plate simply supported along all edges. A nine-node Lagrangian finite element formulation is established and results are presented for simply supported or fixed boundary conditions. Numerical results show that moderately thick piezothermoelastic composites are sensitive to shear deformation, but increasing plate aspect ratio reduces the shear deformation influence.
