Positive temperature in nonlinear thermoviscoelasticity and the derivation of linearized models

R Badal, M Friedrich, M Kružík, L Machill - arXiv preprint arXiv:2407.02035, 2024 - arxiv.org
According to the Nernst theorem or, equivalently, the third law of thermodynamics, the
absolute zero temperature is not attainable. Starting with an initial positive temperature, we …

Thermo-elastodynamics of nonlinearly viscous solids

S Almi, R Badal, M Friedrich… - arXiv preprint arXiv …, 2024 - arxiv.org
In this paper, we study the thermo-elastodynamics of nonlinearly viscous solids in the Kelvin-
Voigt rheology where both the elastic and the viscous stress tensors comply with the frame …

Nonlinear relations of viscous stress and strain rate in nonlinear Viscoelasticity

L Machill - arXiv preprint arXiv:2409.11882, 2024 - arxiv.org
We consider a Kelvin-Voigt model for viscoelastic second-grade materials, where the elastic
and the viscous stress tensor both satisfy frame indifference. Using a rigidity estimate by …
