You can compute stress, factor of safety, and deformation results on selected parts as you perform a Motion Analysis study. You can compute the finite element results at the specified time step, or the entire time range. Stress, displacement, and factor of safety results at the chosen time steps or ranges are displayed on the parts during the motion simulation.
In the Motion Analysis study, after finite element setup and analysis, click Display Stress 
and select from the list of options.
The figure shows the stress plot on a four-bar linkage mechanism at a time step during the motion simulation.
