How to define a nonlinear material in FEA?

In this article, I will tell you the very basics you need to understand to start using nonlinear material models in your FEA simulation. If you are just starting FEA, you may have learned that defining “Material Data” usually meant providing 2 input values into your FEA software: The Young’s Modulus The poisson’s ratio And […]
