Study on the Influence of T Stress Component on the Tensile Initiation Angle of Compression-shear Closed Crack by JIN Songyang, LIU Hui

“…The traditional theory of fracture mechanics only considers the singular stress term in the Williams expansion term of the stress field at the crack tip.There is a big difference between the theoretical predicted value and the experimental value of the crack initiation angle.In order to study the influence of T-stress (non-singular stress term) on the tensile initiation angle of compression-shear closed crack,this paper firstly derives the theoretical solution of the stress near the closed crack tip under the condition of compression-shear stress,and introduces the T-stress into the traditional fracture criterion for correcting the maximum circumferential stress criterion;secondly,carries out the parameter sensitivity analysis for the three cases considering different T-stress components;finally,compares the theoretical predicted value with the experimental value in existing literature.The results show that:The T-stress component has a significant influence on the predicted value of initiation angle of closed crack.It is found by the parameter sensitivity analysis that the critical distance has the greatest influence on the crack initiation angle.At the same time,the predicted value of initiation angle with considering T_x,T_y and T_xy stress components is between that with only considering T_x stress component and considering T_x and T_y components,and with considering of three T-stress components,the predicted value of initiation angle is in good agreement with the experimental values.…”
