Can you provide a litte more detail about what you're looking for? Screenshots or models?
Assuming that you are testing the plate until it breaks, you will have to do a nonlinear simulation to account for yielding prior to the break.
Simulation will not show the material breaking, but if the stress exceeds the known tensile stress of the material that means it broke.
As ryan said, screen shots would be very helpful. Also, the most crucial part of any simulation is to properly define the boundary conditions and loads.
