By determining the zero - energy modes of piezoelectric multilayer element , eight stress modes on piezoelectric sub - element are obtained . 4 . a finite element program for piezoelectric laminates is developed , examples of the piezoelectric laminates are presented to identify the accuracy and the continuity of transverse stress 利用等函数方法推导了正交异性情况下的三维8节点单元所具有的应力模式,并依据多层层合单元的零能模式判据,得到最终具有8个应力模式的应力矩阵。
