A chemo-mechano-thermodynamical contact theory for adhesion, friction, and (de)bonding reactions

This work presents a self-contained continuum formulation for coupled chemical, mechanical, and thermal contact interactions. The is very general and, hence, admits arbitrary geometry, deformation, material behavior. All model equations are derived rigorously from the balance laws of mass, momentum, energy, entropy in framework irreversible thermodynamics, thus exposing all coupling present field constitutive relations. In process, conjugated kinematic kinetic variables thermal, chemical identified, analogies between highlighted. Particular focus placed on thermodynamics bonding distinguishing exothermic endothermic reactions. Distinction also made long-range, non-touching surface interactions short-range, touching contact. For relations, examples proposed discussed comprehensively with particular their coupling. Finally, three analytical test cases presented that illustrate thermo-chemo-mechanical useful verifying computational models. Although main novelty extension existing formulations to contact, sheds new light thermo-mechanical because it consistently basic principles using only few assumptions.
