在这项研究中，我们处理的行为的压电热弹性复合板考虑到横向剪切和耦合之间的机械，热和静电场的影响。作为一个分析模型，我们考虑一个矩形层合板组成的几个纤维增强层和压电层。所有的层被假定为表现出2毫米的对称性和各向异性的主轴与坐标轴重合，即，一个交叉铺设层压板被认为是。我们假设层合板受到机械，热，电载荷与所有的边缘简支和治疗的问题作为一个耦合piezothermoelastics1。通过数值计算分析了横向剪切和耦合作用对层合板性能的影响。此外，控制的偏转所施加的电压进行检查。
In this study, we treat the behavior of a piezothermoelastic composite plate taking into account the effects of transverse shear and coupling among mechanical, thermal, and electrostatic fields. As an analytical model, we consider a rectangular laminate composed of several fiber-reinforced laminae and a piezoelectric layer. All the laminae are assumed to exhibit 2-mm symmetry and the principal axes of anisotropy to coincide with coordinate axes, that is, a cross-ply laminate is considered. We assume that the laminate is subjected to mechanical, thermal, and electrical loads with all edges simply supported and treat the problem as a coupled piezothermoelastic one. Numerical calculation is carried out to examine the effects of transverse shear and coupling on the behavior of the laminate. Moreover, the control of the deflection by applied voltage is examined.
