A framework is developed to predict the constitutive behavior of polymer matrix nano-composites under several parallel damage mechanisms, such as Mullins effect, Hysteresis, and Strain induced crystallization. The framework consists of a visco-elastic platform and several add-on modules to describe different mechanical failures in of Elastomeric Nano-Composites. Each Module represents a micro-mechanical model and thus be derived from the existing models. The novelty of the work lies in the design of the framework which (i) brings different theories of damage together, and (ii) has a compartmented theoretical structure that allows simultaneous modeling of different mechanisms. With the help of recent advances in multi-scale modeling of different damage mechanisms, the proposed framework provides a unique tool that considers visco-elasticity, damage, crystallization, permanent and cyclic damage at the same time to predict the progressive failure of ENC.
