We outline the method here only for the first and second problems of elastodynamics. 在这里我们只针对第一类和第二类弹性动力学问题来概述这种方法。
In this paper, some general theorems and variational principles of the boundary value problem for two time instants in nonlinear elastodynamics are developed. 本文给出了非线性弹性动力学两时端边值问题的某些一般定理及变分原理。
