ABAQUS damaged plasticity model
I am trying, quite unsuccessfully, to model a composite steel frame under dynamic loads. The problem is nonconvergence brought upon by the concrete tensile strains (i think). Apparently ABAQUS kills the analysis once cracks form in the concrete. Has anyone had any success using the "Concrete damaged plasticity model" under cyclic loads and large strains. I have found that researchers use all types of ghetto concrete properties to get convergence, but I am more interested in a better concrete representation.
Any help on this would be greatly appreciated.
