Hi Eden, 
You can calculate the stress and strain in the Ansys mechanical during post-processing. create Geomtery-> mesh the model -> apply boundary conditions-> Right click on the solution and select the stress and strain according to the requirement -> right-click on the solution and select the stress tool -> in the stress tool select the option of " Max Equivalent Stress" then the "stress tool"  will create under the solution tree. Right-click on the stress tool and select the safety margin option there. 


All the best
