If you are running MAPDL interactively, what message(s) do you see in the  output window? The MAPDL output window looks like this:If you are instead solving the model in batch mode, the message(s) will be in the output file. Is the frequency of excitation at or near a natural frequency of this very large plate? If not (if there is no dynamic amplification) then a static analysis should suffice (there would in this case be no need to solve as a transient). Is it your intention to predict either of the two phenomena (ratcheting or shakedown) using a Chaboche material model?


Kind regards,
