Hey guys,

I thought it would be a good idea to dig a little deeper into the non linear FEA topic by presenting a introductionary tutorial. It covers nonlinear material modelling as well as geometric non linearity (i.e. large displacement FEM).

I hope you like it and as always, if you have questions or comments, feel free to add them below :)

I am also struggling with non-linearity problems. Thanks to this channel, I am at least able to increase my knowledge base on that topic . Thanks😍

Do you still have this model? Currently, I don't know how to find this model online to practice.

Thanks for your useful videos. I have a similar problem with left side fixed and right side with imposed translation on nodes. After defined the two load collectors and run successfully a first analysis, i want to change the value of the imposed translation but at this point i'm not able to recover the constraint to modify . I go through "Analysis- constraints" but when window opens i don't see any way to specify which constraint i want to choose. Could you please explain the correct steps to accomplish the task ? Thanks

Hi, I have the curve strain-stress, but the strain is the percent one, not the absolut value. How can I say this information to the software? If I say nothing the 100%, it takes as 100 mm of strain
