A micromechanical model for strain-induced crystallization in rubber

Abstract eng:
A micromechanical model for strain-induced crystallization in rubber-like materials is proposed. Combining the evolution of the crystallization of a single polymer chain with the maximal advance path based homogenization method, we are able to predict this complex process. The crystallization of the material leads to an anisotropic mechanical response, which our model is able to capture. The representative numerical simulation results are in good quantitative agreement to experimental data for both, uniaxial extension and three-dimensional multiaxial simulations of strain induced crystallization around a cracked region.
