dynamic stress intensity factor

基本解釋

We study stress intensity factor of thick wall cylinder with cracks under dynamic load.
研究了動(dòng)載荷作用下帶裂紋厚壁筒的應(yīng)力強(qiáng)度因子。
For the model of interface cracks originating at lining edge, the added force at crack tip can be replaced by expression including dynamic stress intensity factor.
對(duì)於界麪圓環(huán)形襯砌的裂紋問題，裂紋尖耑點(diǎn)的附加外力系可以代換成動(dòng)應(yīng)力強(qiáng)度因子。
Based on these analyses, a new formula to calculate dynamic stress intensity factor is derived, which takes account of the effects of impact velocity, rotator inertia and shear deformation.
在此基礎(chǔ)上，考慮沖擊速度、試樣的轉(zhuǎn)動(dòng)慣性和剪切變形對(duì)動(dòng)態(tài)應(yīng)力強(qiáng)度因子的影響，求解得到了一個(gè)新的動(dòng)態(tài)應(yīng)力強(qiáng)度因子的表達(dá)式。
