| 摘 要： | 从分析非线性粘弹性体单阶跃应力松弛函数的性质入手，指出内蕴时标对应变历程的依赖关系，从而修正了两阶跃应力松弛的表达式。在八种不同情况下，这些表达式的计算曲线与两阶跃应变试验的实测点都很吻合。

| Abstract: | An analysis of the properties of the stress--relaxation function in singlestep strain of a nonlinear viscoelastic system is made first,then the dependence of the intrinsic time scale on the strain histories is pointed out and the expression for the stress-relaxation in doublestep strain is modified. The results of the calculations are in good agreement with experiments for eight cases in doublestep strain histories. |
