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.

Plot Stress-Strain from Ansys Commands using MCalibration
Introduction In this article I will show how you can quickly convert any Ansys material model (in APDL format) into stress-strain predictions using MCalibration. That is, I will show how you can plot stress-strain from Ansys commands using MCalibration. Plot Stress-Strain from Ansys Commands I often receive Ansys dat-files that contain fully defined material models, Read More

Extended Tube Model in Ansys Mechanical
The Extended Tube model is one of the most accurate hyperelastic material models available, but it can be difficult to use if you don't understand how the material parameters influence the predicted stress-strain response. This article will demonstrate that by example.

Parametric Study of the Mullins Effect Model
The Ogden-Roxburgh Mullins effect model is highly non-linear. In this article I will graphically illustrate how the different parameters influence the predicted stress-strain response.
