How to define shear stress for Finite Element Analysis using CATIA V5

The most important thing that we have to do finite element analysis (FEA) using any software is knowing about type of stress that might happen in to the construction of parts such as bending stress, shear stress, pressure, tensile, etc. Generative Structural Analysis menu in CATIA V5 has distributed force, moment, bearing load, force density, etc. Which one could we use to describe the shear stress or do you have another way to do analysis based on shear stress?
