Abstract

This work proposes a novel GENERIC-based thermodynamically consistent (TC) time integration scheme for discrete thermoelastodynamics. Its main contribution relies on the fact that the formulation proposed makes use of the temperature to describe the thermodynamic state which has so far been believed unreachable within the GENERIC approach. As expected, this election makes the new TC scheme overcome the reported drawbacks found in the already developed entropy formulation. Proof for these claims as well as numerical examples that illustrate the performance of the novel scheme are provided and will be exposed in the oral presentation
