Abstract

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.
