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 […]

Safety factor: How do I calculate that?

This article talks explains the concept of safety factor and how it is calculated. It’s a fundamental notion that every mechanical engineer have to understand well. How do I know if the design of my part is « safe » enough? That’s a difficult question that many designers asked themselves. One of the potential answers involves the […]

Plate with a hole analysis : FEA Basics

The plate with a hole ! Who didn’t start to learn FEA by this simple example ? I remember when i modeled for the first time this plate on the first NASTRAN in DOS during my FEM course, what a memorable moment… i had to run the program like a hundred times before getting a […]
