Soft polymer foams, and some other materials, often exhibit different stiffnesses in uniaxial tension and compression. Most material models cannot predict this type of behavior, but there are some excellent choices for this.
A material model is considered Drucker’s stable if an increase in strain results in an increase in stress. In some cases it can be important to enforce that a material model is Drucker’s stable. This article shows how you can easily achieve this in MCalibration.
It is easy to create stress-strain plots for any Abaqus material model using MCalibration. This article shows how.
In this article I will show how you can quickly convert any Ansys material model (in APDL format) into stress-strain predictions using MCalibration. Here are
