I am modelling large direct shear test in Abaqus Standard (300 x 300mm box). While shearing for a displacement of 4 mm the model aborts due to convergence issue. I am using Mohr coulomb plasticity model, I hope my model parameters are fine. I guess the issue is with the meshing. I have tried remeshing rule which improved the strain a bit further but still I couldn't shear for a displacement of 20 mm. Is there any option to be specially taken care while modelling large strain problems. I am using the quad element and activated Distortion control also. I have kept the length ratio as 0.1 itself. For the shearing region I have given Quad modified and sweep the element with advanced algorithm as re-meshing rule will be applied only for those elements.
It will really helpful if some one can help me to sort out this problem
Thanks in advance.
