摘要
本文提出一个适合于率型本构方程的边值-初值问题的广义变分原理,此原理是在现时构形上以卷积形式给出,可用于建立大变形分析中适时的Lagrange描述的增量分析公式。
In this paper, a rate-type generalized variational principle,which is applicable to the boundary-initial value problems in hypo-elasticity, is presented. The principle is given in the convoluted form in current configuration, and thus, can be applied to construct the incremental formulatioms of updated Lagrangian description.
