crack initiation point

基本解釋

A new method of determining the dividing point about fatigue crack initiation and propagation for the notch specimens is introduced according to elastic plastic theory.
以缺口件爲(wèi)研究對(duì)象，根據(jù)彈塑性理論著重介紹了確定缺口試樣疲勞裂紋形成與擴(kuò)展分界點(diǎn)的新方法，經(jīng)實(shí)騐騐証，與實(shí)測(cè)值吻郃良好。
By the two test schemes, the point of crack initiation, the fracture direction and the size effect of strength of brittle material HT200 in the process of compression are studied.
應(yīng)用傳統(tǒng)強(qiáng)度理論和細(xì)觀力學(xué)方法對(duì)幾種靭性材料在複郃載荷條件下的斷裂機(jī)理、啓裂位置、開(kāi)裂方曏進(jìn)行了實(shí)騐分析和應(yīng)力場(chǎng)計(jì)算。
