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(yīng)變或預(yù)應(yīng)變，在某種情況下，能夠縮短以后的疲勞壽命。
The results show that low cycle fatigue life is reduced and cyclic stress is raised by torsional prestrain raising.
結(jié)果表明，扭轉(zhuǎn)預(yù)應(yīng)變降低低周疲勞壽命，循環(huán)應(yīng)力隨扭轉(zhuǎn)預(yù)應(yīng)變的增大而增大。
Both the maximum recovery stresses of TiNi and TiNiCu alloys increase with increasing prestrain level.
結(jié)果表明: 二元與三元合金在一定溫度范圍內(nèi)的最大回復(fù)力隨著預(yù)應(yīng)變的增大而升高, 但是當(dāng)預(yù)應(yīng)變達(dá)到或超過其最大可恢復(fù)變形極限時最大回復(fù)力反而減小。
