In this short tutorial, we are going to be reviewing Non-Linear Materials in Simcenter 3D (NX CAE). Throughout this demonstration, we are going to be using 4340 steel to discuss what happens after the material has yielded.
Creating Material Nonlinearity Models
There are two ways of creating Material Nonlinearity Models:
The following represents the material non-linearity models that can be set up in Simcenter.
The list below shows what models exist for each solution type. The solution types that are used in this tutorial is SOL 106, SOL 401 and SOL 402.
Defining Stress-Strain Related Properties
Stress-Strain (H): Inside this form, you can see there is a “Stress-Strain (H)” field. Depending on your material model you can define a plastic modulus, your stress-strain curve, or you can define only the plastic part of a stress-strain curve.
Initial Yield Point (LIMIT1): It is important that you have the Initial Yield Point at the same location on your material yields (matches stress-strain curve location).
