I spent some more time converting Engineering Stress and Strain to True Stress and Plastic Strain. Last week, I used a YouTube video from an Abaqus user.  Today I watched the Ansys How To video on Metal Plasticity.

As I revised my spreadsheet, I found a mistake. When I did the copy/paste of the stress from column E to column G, I didn’t paste the values, but the formulas, so I got the wrong numbers in that column! You will want to revise the values in your model if you copied this mistake.
