Numerical prediction of strain-induced crystallization under complex loadings

CRC Press eBooks, pp. 145–150

Abstract

In this contribution, strain-induced crystallization of natural rubbers under various loading scenarios is investigated numerically. To this end, a computational framework is constructed on the basis of a recently developed theory for strain-induced crystallization ( Khiêm et al. 2022b ). Its prediction is validated with infrared thermography-based quantitative surface calorimetry measurements under equibiaxial loading condition ( Khiêm et al. 2022a ). Finally, generalization of the computational model in biaxial tension with different biaxiality ratios will be used to analyze the self-reinforcement mechanism in natural rubbers.
