As headrush says, you don't need any strength parameters in mechanica. It will calculate stress and dispalcement based upon the applied load and the modulus of the material. Simply stated, you'll then determine if the stress is too high based upon the FEA calcualted stresses and the actual material strengths. Be careful with any FEA program as it's fairly easy to get pretty pictures that are in reality useless b/c the constraints and/or loads don't represent the real world conditions.

I hope this helps too.
