Elastomer Rate Dependence

Stress-Strain Behavior of Thermoplastic Polyurethane

2.3 Time-Dependence Figure 5 shows the true stress-true strain curves to εmax =1.0 at three different compression strain rates, i.e. ε 1 = 0.01/ s, 0.05/ s ε 2 = , and 0.1/ s ε 3 = . For the loading portions of the curves, the higher the strain rate, the larger the stress. The unloading
