Effect of a Post-Fatigue Damage on the Residual Dynamic Behavior of Advanced-SMC Composites

The purpose of this article is to investigate the effect of an initial pre-damage induced by a fatigue loading on the tensile dynamic behavior of Advanced Sheet Molding Compounds (A-SMC). Tension-tension fatigue preloading at a frequency of 30 Hz is performed at various applied stress levels prior to subject the A-SMC specimens to tensile tests at different strain rates, namely: 10−3 s−1 (quasi-static), 1 s−1 and 60 s−1. The developed...
