Research paper thumbnail of Variational models of thermo-viscoelastic damage in finite strains: local and nonlocal approaches applied to polymer behavior

Their microstructural features are responsible for challenges that must be addressed for accurate constitutive modeling, including thermomechanical coupling, large strain phenomena, viscosity effects and particular degradation behavior, among others. This thesis aims to tackle this problem within the framework of variationally-formulated constitutive modeling of dissipative phenomena. This type of energy-based approach allows for an efficient treatment of multiphysics coupling, while accounting for dissipation in a thermodynamically sound manner. Formulations for a wide range of thermo-viscoelasticity phenomena in finite strains are presented, with an emphasis on the coupling mechanisms and on the chosen parametrization of all dissipation sources. Similar variational approaches can be extended to the pr...
