摘要
根据复合型裂纹应力强度因子解析计算方法对不同的裂纹尺寸、荷载大小对应力强度因子的影响进行仿真研究,得到了不同情况下的应力强度因子.给出了I、II复合型裂纹应力强度因子随裂纹尺寸深度变化的情况,并对这两种情况下的应力强度因子进行了比较.
According to the analytic method of the stress intensity factor of the composite crack, simulations have been made on the influences of various cracks sizes and loads on the stress intensity factor. Different stress intensity factors have been achieved in various situations. Rules of type I and II stress intensity factors of the composite crack have been given by the depth of the cracks. And comparisons of the stress intensity factors have been made between the two situations.
