| 摘 要： | 在已有非线性粘弹性本构关系的基础上．运用连续介质损伤力学方法．得到了一个考虑损伤的非线性粘弹性本构关系．并通过对在不同应变率条件下的单轴拉伸实验的理论研究．验证了考虑损伤的非线性粘弹性本构关系更适合于对非线性粘弹性材料的力学行为进行描述的结论．

| Abstract: | In this paper, the nonlinear viscoelastic constitutive relation with damage which is based on the proposed nonlinear viscoelastic constitutive relation is obtained by means of continuum damage metho d (CDM). The result that the nonlinear viscoelastic constitutive relation with damages is more suitable for describing the mechanical behaviors of nonlinear viscoelastic materials than the nonlinear viscoelastic constitutive relation is ver ified by comparison between the theoretic calculated results and experimental da ta about the experiments under different strain rate levels for improved polypro pylene. |
