A3 Fatigue in Polymers (Hysteresis Heating)

Title

Unlike metallic fatigue (dominant crack growth, Metallurgy A1), in polymers the viscous component (tan delta, M3) dissipates energy in each cycle as heat, being able to raise the local temperature to softening before the crack mechanism dominates.
