After an analysis of the 3D stress field on a Model CD350 drill pipe elevator, the stress intensity factors(SIFs) of the surface corner crack with different depths and shapes on the critical section are worked out by the finite element displacement method, and the pattern of variation of SIFs along the front of the crack is presented.
对CD350钻杆吊卡三维应力场进行了分析,进而采用有限元位移法求解危险截面处不同深度和不同形状表面角裂纹的应力强度因子。
