Inelastic dissipative polymer based composites under fully coupled thermomechanical processes

Overview & Synopsis

The aim of this work is to develop a multiscale framework for polymer based composites made of generalized standard materials with nonlinear behavior, that accounts for fully coupled thermomechanical processes. To achieve that, the classical homogenization theory for mechanical processes has been extended to include the thermodynamic laws, leading to a proper framework for both microscopic and macroscopic response of the composite. With the aid of this framework, full-field (periodic homogenization) and mean-field (Mori-Tanaka/Transformation Field Analysis) approaches gave been designed and validated. Numerical examples demonstrate the model’s capabilities and limitations.
