I was looking up some fracture mechanics techniques using XFEM.. My problem is a plate with edge crack pure mode 1 loading. In the outputs of XFEM contour integrals. I requested for 5 contours.. Each contour gives different values of K.. (SIF) there are two things.. here.. XFEM_1 results are one thing and XFEM_2 results are totally another.. What are those XFEM_1 and XFEM_2 in output database.. ? Anybody ? ABaqus manual ddoesnt mention it at all. Can someone give a detailed practical tips to use XFEM for contour integral calculation and especially how to look for and how to make sense out of results n know we have got correct ones.. Thanks in advance
