The Contour Integral and extended finite element methods (XFEM) are two methods for calculating stress intensity factors and J-integrals in Abaqus.
In this tutorial, The calculation of the J-integral in the Compact Tension specimen via Abaqus using the Contour Integral method in 2D and 3D spaces is explained according to a paper.
The complex procedure of creating a focused “spider web” mesh with elements concentrated at the crack tip is explained in detail. In addition to using an appropriate mesh pattern, the crack singularity settings are done to finally obtain the most accurate answer without generating too many elements in the crack tip region to reach accurate results.
