dynamic stress intensity factor

基本解释

We study stress intensity factor of thick wall cylinder with cracks under dynamic load.
研究了动载荷作用下带裂纹厚壁筒的应力强度因子。
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.
对于界面圆环形衬砌的裂纹问题，裂纹尖端点的附加外力系可以代换成动应力强度因子。
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.
在此基础上，考虑冲击速度、试样的转动惯性和剪切变形对动态应力强度因子的影响，求解得到了一个新的动态应力强度因子的表达式。
