The Drucker Stability condition is well know, but not trivial to understand. This article explains what this condition means, and how to use it in your own work.

Sometimes it is possible to calibrate a viscoplastic material model to a single monotonic tension curve. This article has the details.

In this article I will explore how useful the new AI tool ChatGPT from OpenAI is for topics related to polymer mechanics.

If you repeat a material model calibration multiple times, should you expect the optimal material parameters to be unique?

This article demonstrates one problem that can occur if you calibrate a material model without considering the initial Young’s modulus

The commercial FE solver Radioss from Altair is now open source! This article shows how to download, compile, and use the OpenRadioss.

Did you know that almost all FE simulations underpredict the residual strain / displacements in BENDING. This article explains why.

Did you know that it is possible to predict permanent set using a viscoelastic material model? This article explains how.
