crack initiation

基本解釋

Our study points out that this test actually reflects the ability of material to resist creep crack initiation and propagation under multiaxial stress state.
研究表明，標(biāo)準(zhǔn)缺口持久試驗(yàn)的實(shí)質(zhì)是反映材料在多向應(yīng)力作用下的抗主裂紋萌生與擴(kuò)展的能力。
As the fleet ages, there's an increasing need for embedded wireless strain sensors capable of detecting and tracking accumulated strains --"precursors" to crack initiation, according to the official.
隨著機(jī)群服役時(shí)間的增加，對(duì)嵌入式無(wú)線應(yīng)力傳感器的需求也在不斷的增加，通過(guò)這些傳感器對(duì)應(yīng)力積累進(jìn)行探測(cè)和跟蹤，避免飛機(jī)機(jī)體發(fā)生可能的疲勞和破裂。
