Foam Fatigue and Cyclic Testing


Industry:

foam

fatigue

cyclic stability

Background

Foams can be very complex, with highly varied degrees of firmness, resilience, relaxation, creep, and fatigue behaviors. This study builds on the “Foam Stress Strain Resilience” and the “Foam Relaxation and Creep Recovery” applications and introduces additional fatigue metrics. Foams are frequently deployed in applications in which they also experience thousands of cycles. This study evaluates the fatigue of foams over ten cycles to illustrate how foams behave at the onset of cyclic fatigue. The TA.XTPlus Texture Analyzer can conduct thousands or millions of cycles, so the metrics of this study can be customized to suit a specific application.
