摘要
研究了动载荷作用下带裂纹厚壁筒的应力强度因子 .结果表明动态应力强度因子的最大值在加载时间上有滞后性现象 ,它的最大值随厚壁筒尺寸增加而增加 .同时 ,发现动态应力强度因子比相应的静态应力强度因子大 .
We study stress intensity factor of thick wall cylinder with cracks under dynamic load. The result indicates that the maximum of dynamical stress intensity factor arrives behind the load time and increases with the size of thick wall cylinder. Meanwhile, we find the dynamical stress intensity factor is bigger than the statical stress intensity factor under the same conditions.
