I have a 2D model in abaqus (Explicit) and analysis is quasi-static (with time 50). Material model is damage plasticity. I can see some crack in my model. But when I refine mesh, displacement will be very large and show no converging in solving.
Please help me on how I can solve this problem.
There is never any convergence issue in Explicit. You always get some solution based on your model setup. You have to check the correctness of the solution such as by analyzing the deformed shape, history plot of energies, etc.
I understand that the kinetic energy in my model is very large (e6) and cause the wrong result. I use of longer time in my model and I reform the mass scaling in step module but it could not help me. please help me. I am working on this problem 3 weeks.
thank you. I have found the answer to my question. I have found that abaqus explicit cant solve the complex problem, for example many element with many interaction and many constrain. this kind of problem cause the wrong solving. I could get the true results with reducing the number of element of 53000 to 12000. I'm not sure that this answer be the right solution but this could remove any problem in my model.
