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。 Material description method was used to select the initial configuration as the reference configuration. The viscoelastic large deformation constitutive relation and the finite element equation which were expressed by Kirchhoff stress and Green strain were deduced and solved by Total Lagrangian method. Satisfactory results were obtained.
