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

### Linear Viscoelasticity – Part 5 – Storage and Loss Modulus

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

### Linear Viscoelasticity – Part 4 – Prony Spectrum

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.

### Linear Viscoelasticity – Part 3 – Multiaxial and Large Strains

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

### Linear Viscoelasticity – Part 2 – Solve the Equations

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.

### Linear Viscoelasticity – Part 1 – Derivation

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.
