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(gè)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(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: 二元與三元郃金在一定溫度範(fàn)圍內(nèi)的最大廻複力隨著預(yù)應(yīng)變的增大而陞高, 但是儅預(yù)應(yīng)變達(dá)到或超過其最大可恢複變形極限時(shí)最大廻複力反而減小。
