分析了在机械、热和电载荷作用下压电热弹性层合板的非线性动力学行为。基于von Kármán应变和一阶剪切变形理论，采用Galerkin方法对层合板的非线性变形进行了分析。讨论了屈曲温度、大的静挠度和无限小振动或有限振动的固有频率。研究了横向剪切对非线性行为的影响，以及通过在压电作动器上施加电压来提高屈曲温度、线性化热挠度和固有频率的方法。
Nonlinear dynamic behavior of a piezothermoelastic laminate subjected to mechanical, thermal, and electrical loads is analyzed. Nonlinear deformation of the laminate is analyzed based on the von Kármán strains and the first-order shear deformation theory using the Galerkin method. The buckling temperature, the large static deflection, and the natural frequencies of infinitesimal or finite oscillation are discussed. The effect of transverse shear on nonlinear behavior and the methods to raise the buckling temperature, and linearize thermal deflection and the natural frequencies, by applying the electrical voltage to piezoelectric actuators, are investigated.
