This is possibly because you are solving an elastic problem and not an elasto-plastic one.

In order to account for plasticity, it is important for the material defined to have bilinear isotropic hardening property specified. However, this is not enough, and we also need to switch ON plasticity by selecting the plasticity model to be used under Material assignment settings as shown below. By default this option is set to "none".


Here is a video tutorial that talks about defining a plasticity problem end to end. Hope you find it useful

Please let me know if the suggestion is helpful or in case the problem still remains.
