摘要
采用物质描述法,选择初始构形作为参考构形,导出以Kirchhoff应力和Green应变表示的粘弹性大变形本构关系和有限元方程,利用Total Lagrangian增量法进行求解,取得了满意的结果。
Using material formulation method, and choosing initial configuration as reference , the viscoelastic large deformation constitutive relation and the finite element equations denoted by the Kirchhoff stress and Green strain are derived. The equation is solved by use of the Total Lagrangian incremental approach. Satisfactory results are obtained.
