In this talk, I will present a macroscopic phase-field theory seemingly capable of explaining, describing, and predicting all of the classical and recent experimental observations on the internal fracture of rubber: from the nucleation of cavities/cracks, to their growth to micro-cracks, to their continued growth to macro-cracks, to the remarkable healing of some of the cracks. Following the outline of the theory, I will present its numerical implementation as well as comparisons with the classical poker-chip experiments of Gent and Lindley (1959) and recent experiments due to Ravi-Chandar.
