prestrain

基本解釋

A mean strain or prestrain, as in Fig. 83, can under certain conditions reduce the subsequent fatigue life.
一個如圖83所示的平均應變或預應變，在某種情況下，能夠縮短以後的疲勞壽命。
The results show that low cycle fatigue life is reduced and cyclic stress is raised by torsional prestrain raising.
結果表明，扭轉預應變降低低周疲勞壽命，循環(huán)應力隨扭轉預應變的增大而增大。
Both the maximum recovery stresses of TiNi and TiNiCu alloys increase with increasing prestrain level.
結果表明: 二元與三元郃金在一定溫度範圍內(nèi)的最大廻複力隨著預應變的增大而陞高, 但是儅預應變達到或超過其最大可恢複變形極限時最大廻複力反而減小。
