摘要
本文把采用Laplace变换和有限元求解粘弹性力学问题的方法由各向同性材料推广到正交各向异性材料;其中,通过引入广义时间的概念,提出了一个实用Laplace变换的数值反演方法.
The laplace transform and finite element methods for solving mechanical problem are extended in this paper from istrotopic material to orthotropic and a numerial inversion of the lapace transform is proposed by introducing the generalized time concept.
