Residual stress, carbon profile, and phase volume fractions are all important considerations when modeling a loading condition for a steal part after heat treatment. ANSYS Mechanical and the DANTE material model subroutines can be used to predict and import results such as residual stress, carbon profile, and phase volume fraction into a loading model.

By mapping in the residual stress from heat treatment, the residual compressive stress on the surface is a lot greater since it is the combination of the compressive residual stress and loading stress. However, the residual compressive stress counteracts the tensile stress on the bottom surface of the midsection which reduces the overall bending stress.
