What is Work Hardening ?
Work hardening or strain hardening is a process through which the yield strength and hardness of a metal are increased by plastic deformation. Consider the hypothetical stress strain curve shown below for a metallic specimen:
How to input a stress-strain curve in ANSYS Workbench?
ANSYS and Plastic Strains ANSYS workbench is rather unusual in how it takes inputs for stress-strain curves. Typically, the strain data in stress-strain curves represents total strain. ANSYS workbench requires that the user inputs plastic strain instead of total strain. The total strain must be converted into plastic strain before it can be used with…

Converting Total Strain into Elastic and Plastic Components
This spreadsheet lets you convert total strain into its elastic and plastic components. You have to input values for Young’s Modulus, Total Strain and Total Stress – Make sure that the Young’s Modulus and Total Stress have the same units: Strain Converter Stress Total Strain Elastic Strain Plastic Strain 0 0.00000 0.00000 0.00000 10,443 0.00049…
