How can I model to express strength degradtion?

Hello!
I built a cantilever beam with concrete04model.
I wanted to see strength degradation on stress and strain curve when the model was under static cyclic loads.

But all loops were same.
I didn't see any strenght degradation.

So if i want to see stregnth degradation, what should I do?

Thank you for your help.

have you set the element geotransf "linear",if you set "linear" you cannot see the strenght degradation ,because the matrix cannot be solve when you push
