The interplay of fatigue damage and inelasticity of elastomers is an open problem. A viscoelasticity-based constitutive equation's parameters were used to trace the evolution of elastomer inelasticity with fatigue damage. Contrary to the Continuum-damage-mechanics based hypothesis, the decay of stiffness of the equilibrium network was non-monotonic with fatigue life. The variation of the inelastic network parameters suggests interplay between damage and inelasticity. However, a trend suggestive of the effect of damage on viscoelasticity was not found. High-temperature fatigue demonstrated no permanent effect on stress–strain response. The results indicate that the degradation of stiffness is not an indicator of fatigue-induced damage.

弹性体的疲劳损伤和非弹性之间的相互作用是一个悬而未决的问题。基于粘弹性的本构方程的参数用于追踪弹性体非弹性随疲劳损伤的演变。与基于连续介质损伤力学的假设相反，平衡网络的刚度衰减与疲劳寿命是非单调的。非弹性网络参数的变化表明损伤和非弹性之间存在相互作用。然而，没有发现表明损伤对粘弹性的影响的趋势。高温疲劳对应力应变响应没有永久性影响。结果表明刚度的退化不是疲劳引起的损坏的指标。
