elastic perfect plastic- cyclic load

[albert1981]

Dear all,

I am doing an elastic perfect plastic analysis applying a cyclic load. I am doing a quarter of plate with a notch in the centre applying symmetric boundary condition. I am loading 10% of the load each time and so for the unloading. I can not finish the analysis becase of convergence problem.
Can you please help me?

Thanks,
Albert

albert1981,

Convergence problmes can be caused by many reasons. To get a good response you will have to describe the error message.
Do you have enough constraints to constraint the part in all 3 directions?

How far the analysis have ran?
