... history at low-rate loading [ 24 – 26 ]. A number of studies assessed the effect of plastic prestrain on high cycle fatigue and fatigue crack growth behavior [ 27 , 28 ]. The results suggest that plastic prestrain enhances fatigue life and delays the crack growth rate. During dynamic tensile testing...
