prestrain

基本解释

A mean strain or prestrain, as in Fig. 83, can under certain conditions reduce the subsequent fatigue life.
一个如图83所示的平均应变或预应变，在某种情况下，能够缩短以后的疲劳寿命。
The results show that low cycle fatigue life is reduced and cyclic stress is raised by torsional prestrain raising.
结果表明，扭转预应变降低低周疲劳寿命，循环应力随扭转预应变的增大而增大。
Both the maximum recovery stresses of TiNi and TiNiCu alloys increase with increasing prestrain level.
结果表明: 二元与三元合金在一定温度范围内的最大回复力随着预应变的增大而升高, 但是当预应变达到或超过其最大可恢复变形极限时最大回复力反而减小。
