Micro Abstract:
The strain-induced crystallization (SIC) in polymers is a phenomenon manifesting itself as the natural reinforcement caused by the high deformation. The current presentation, treats a polymer affected by the SIC as a heterogeneous medium consisting of regions with a different degree of network regularity. Such a concept allows us to simulate the nucleation and the growth of crystalline regions. The model proposed is based on the assumptions for the free energy and dissipation potential.
