Happy New Year 2023 :) I can’t believe this blog has 10 years! Today, let’s talk about a few questions that I get all the time: What does linearity means? What is the difference with nonlinear simulation? When do you actually need nonlinear simulation? Video: Let’s talk first about the concept of linearity Linear static […]

## How to determine Weibull Law Parameters with Python? (Part 2)

This article is a second article on the Weibull Law which explains how to use Python to calculate the law’s parameters. If you didn’t read the first article, you can read it here 1 How to determine the parameters of the Law If we start from the Weibull Probability that we determined previously: After a […]

## How to use Weibull Law to identify a better rupture criterion for Brittle Materials? (Part 1)

Today, Let’s talk about some basics of ductile and brittle materials… and how you can find an appropriate failure criteria for brittle materials with defects! I registered an audio file to make it more easy to understand, I hope this subject will interest you! 1 Rupture criterions for ductile and brittle materials Usually, when we […]

## Understanding Dynamics and the effect of Mass

I have been in France for few weeks now… and I had to take the French TGV train very often… That’s when I started to have some weird thoughts and remembered a problem I thought about a lot when I was younger… I decided to write about it now that I have a bit more […]

## 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 […]

## What is Damping and why is it useful?

What is Damping? I am starting with a big question today :) …and to answer this question, we have to understand a few things about dynamic analysis first… Because only a part moving in some way experiences damping… Damping is basically an attenuation of this movement due to some kind of friction If you hadn’t […]
