Modelling the forming of a solid part

Hi,

I want to model the forming procedure for a part similar to what is shown in the picture below. It is not a flat plate element but more like a square rod which is bent in a Z shape. As I understand it, the best way to do this will be with solid elements but there doesn't seem to be a way to do this other than with a pipe forming simulation. Can anyone advise me on similar tutorials? It is important I model the stresses due to forming very accurately.

Thanks
