Micro Abstract:
We propose a micro-mechanically motivated material model for strain-induced crystallization in rubbers. Our point of departure is constructing a micro-mechanical model for a single crystallizing polymer chain. A thermodynamically consistent evolution law describing the kinetics of crystallization in the chain level is then proposed. The chain model is incorporated into the affine full network model. Finally, the numerical performance of the model is compared to the experimental data.
