A Study on Coupled Thermo-Elasto-Plastic-Damage Dissipative Phenomena: Models and Application to Some Innovative Materials

Abstract

This is a review paper on some irreversible thermodynamics-based constitutive models capable of capturing complex dissipative physical bahaviour in multifunctional innovative materials. The thermomechanical response of such materials accounts for two basic sources of material nonlinearity, plasticity and damage, which may result in various failure mechanisms. A number of couplings, such as thermo-elastic-damage, elastic-plastic hardening, plastic-damage hardening, thermo-elastic-plastic-damage, etc., are discussed. Various material symmetry classes, including anisotropy, orthotropy, transverse isotropy, are referred to some innovative materials, such as composite materials, functionally graded structures, thermal or wear resistant coatings, etc. Examples of implementation of chosen models for simulation of some initial boundary problems are presented.
