dynamic stress intensity factor

基本解释

We study stress intensity factor of thick wall cylinder with cracks under dynamic load.
研究了動載荷作用下帶裂紋厚壁筒的應力強度因子。
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.
對於界麪圓環形襯砌的裂紋問題，裂紋尖耑點的附加外力系可以代換成動應力強度因子。
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.
在此基礎上，考慮沖擊速度、試樣的轉動慣性和剪切變形對動態應力強度因子的影響，求解得到了一個新的動態應力強度因子的表達式。
