NonLinear Analysis does not solve completely

NonLinear Analysis does not solve completely

I am trying to solve the attached model. I am using sol 601, the material is nonlinear and is defined by stress strain data from th manufacturer. I load the model with moment that is gradually added. I defined the moments in a table and they increase with time. The time is to 20 seconds. The time steps are 0.05 and the number of time steps is 400. I am using automatic time stepping and large strains are activated.However, I can only solve the model up to 0.5 s. Even when I channge the load to forces or impose displacements, I can solve only up to a certain about of time. The material is non-linear
What can be causing this problem?
