通过罗恩早已提出的一条简单而统一的新途径,系统地建立了压电弹性薄板动力学的虚功原理和8类变量、6类变量、4类变量与2类变量非传统Hamilton型变分原理。这种新的变分原理能反映动力学初值-边值问题的全部特征.
The principle of virtual work, eight-field, six-field, four-field and two-field unconventional Hamiltontype variational principles for elastodynamics of piezoelectric thin plate are established systematically in a simple and unified way proposed by Luo. The new variational principles can fully characterize the initial-boundary-value problem of this dynamics.
