To ensure that JMAN is working
correctly, we will compare the values of K (the stress intensity factor) obtained with both JMAN and Abaqus.
In that purpose, we will create a standard fracture test model for mode I fracture in Abaqus.

Then we can export the
obtained displacement field in an Excel file and analyse it with JMAN. We want to verify that we obtain the same value of K but also the same stress and strain fields.
For convenience, we only compared those values for a few elements randomly chosen in the mesh.
The results obtained with JMAN an Abaqus were similar, we are now going to test JMAN with experimental results.
