摘要
运用非线性粘弹性本构理论中的弹性回复对应原理 ,得到了一个简单的适用于非线性粘弹性材料的瞬时弹性本构关系 ,并结合实例分析 。
In this paper, a simple instantaneous elastic constitutive relation for nonlinear viscoelastic materials is obtained by using the elasticity recovery correspondence principle in nonlinear viscoelastic constitutive theory. The result that the nonlinear viscoelastic constitutive relation being charactered by the instantaneous elastic constitutive relation can correctly describe the mechanical behavior of nonlinear viscoelastic material is verified by comparison between the theoretic calculated results and experimental data about the experiments under different strain rate levels for improved polypropylene.
