Abstract

Polyisoprene rubber exhibits a strain-induced stiffening response upon monotonic loading as well as hysteretic response upon unloading, induced by the kinetics of crystallization. This is further influenced by the high strain-rates experienced in impact problems. These effects of material behavior translate to a rich range of nonlinear wave phenomena including the formation and propagation of shocks and phase boundaries. In this presentation, these nonlinear wave phenomena will be explored through a series of specially designed experiments, with appropriate diagnostics to obtain spatio-temporally resolved kinematic measurements, and then through numerical simulations.
