Evotech CAE | MSC Apex 'Course Bites' | Non-Linear FEA Materials

Here's another 'Course Bite' from our 'Intro to Non-Linear FEA with MSC Apex' online course.

The stiffness of many materials will change as a function of load application and deformation.

Here we'll look the parameters require to define and control this non-linear behaviour Linear analysis assumes constant material stiffness as load is applied.

In this section we look at the change to this stiffness as a ductile material exceeds the yield stress.

In defining the non-linear material behaviour, we need to specify the material stress/strain relationship up to and past the point of yield.

There are a number of methods for defining both the yield behaviour and the post-yield response.

You'll gain a full understanding of these criteria and how they can be applied to your models.
