In this tutorial for Salome Meca with Code Aster, I will talk about:

- What is nonlinear quasi static simulation
- Some of the theoretical aspects that you need to understand for nonlinear simulation
- How to change the plate with a hole model into a nonlinear simulation
- How to enter the strain hardening curve in code aster
- How to control the solution to make it converge

I hope you’ll learn a lot!

This video is a following the previous tutorial where I talk in details about the linear static simulation of the plate with a hole. If you haven’t followed that tutorial, I advise you to start there first before going into the nonlinear part!

**Here’s the video:**
