摘要
本文利用 Truesdell 应力率给出了次弹性力学问题的一个广义变分原理,该原理是在现时构形上以率的形式给出,可用于建立大变形分析中适时的Lagrange 描述有限元公式。
A generalized variational principle for hypoelasticity is presented by using Truesdell stress rate.The principle is given in rate form in current configuration,and can be applied to form finite element formulation of updated Lagrangian description for problems of large deformation.
