Category: Linear Viscoelasticity

This article explains how you can know if a material is linear or non-linear viscoelastic. A few simple tests are all that is needed.

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

This article explains how you can calibrate a viscoelastic material model to DMA temperature sweep data alone.

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

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.

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

This article shows that the WLF equation is always the same or better than the Arrhenius model.

Most people assume that the volumetric relaxation is zero in a Prony series. This article demonstrates a different approach that can be better for some materials.

Time-Temperature Superposition (TSS) is an excellent tool when a material is thermorheologically simple. This article explains how.
