This article explains the foundation and multinetwork structure of the PolyUMod TNV material model and why it is so accurate.

The integral equation form of linear viscoelasticity is identical to a rheological model with parallel spring-and-dashpot networks.

Explanation of how linear viscoelasticity can predict the response due to a dynamic load. The focus is on the storage and loss modulus.

Combined hardening plasticity is perhaps the most interesting type of plasticity model. This article explains how to use this type of model.

A Prony Spectrum is a very useful concept that will help you calibrate and use linear viscoelastic models. This article explains how to do it.

This is part 3 of my series on Linear Viscoelasticity. The focus of this article is on making the calculations large strain and multiaxial.

This is part 2 of my series on Linear Viscoelasticity. The focus of this video is on how to calculate the stress response in a numerically efficient way.

This is part 1 of my series on linear viscoelasticity. The focus is on how to derive the stress response in uniaxial loading at small strains.

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

What is the Gough-Joule effect and how to model it in a finite element analysis? This article explains it all.

This article demonstrates one common mistake that people make when they generate a TTS Master Curve from DMA data.
