Study on Stress Intensity Factor of Two Dimensional Unilateral Crack Based on Finite Element Method

摘要

The relationship between stress, displacement of the crack tip and stress intensity factor is mainly discussed. Calculating K1 of type I crack by finite element software ABAQUS. The effects of different crack forms and the corresponding stress intensity factors on the mesh size are compared. Research results show that: The refinement of the mesh and the optimization of the crack form can improve the accuracy of the calculation results.
