Dear all,
I am trying to do constant triaxiality RVE analysis using ABAQUS. Refereed paper is attached. Before going for full analysis, I tried 2D single element test with user defined MPC. I made use of spring element, equation constraints and user defined MPC as explained in the papers.
But it seems that MPC is not working. After applying the displacement in one direction, I am getting deformation in other direction similar to the condition as if there are no constraints.
I think I am missing somewhere in the modelling part.
I have attached a slide explaining the problem, FE mdoel, input file and MPC.
It will be great if someone can help me.
regards,
Thanks,
