What Material Model Can Predict Different Stiffnesses in Tension and Compression?
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.
How to Force Drucker’s Stability in MCalibration
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.
Material Modeling of Polymers
Here is a presentation about (non-linear) material modeling of polymers. I gave the presentation on 2021-06-24.
Plot Stress-Strain from Abaqus Material Commands using MCalibration
It is easy to create stress-strain plots for any Abaqus material model using MCalibration. This article shows how.
Plot Stress-Strain from Ansys Material Commands using MCalibration
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
MCalibration Material Model Templates
MCalibration supports not only a large selection of pre-defined material models, but you can also define your own material model using a Template.
