| description | As an important fracture parameter,the stress intensity factor plays a crucial role in the fracture analysis of engineering components. Based on the theory of J<sub>2</sub> integral and the bending theory in material mechanics,this paper analyzes the stress intensity factors of 60 degree thin-walled equiangular steel corner cracks and edge cracks under tensile and bending loads,and gives a simple and practical method to determine the stress. The method of the intensity factor,the method given can obtain a closed solution,and the calculation is simple. The results are compared with the finite element solution,and the effectiveness of the calculation method is further pointed out. |
