On the constitutive modelling of fatigue damage in rubber-like materials

A finite-strain hyperelastic phenomenological constitutive damage model is proposed to model the rate-independent failure behavior of rubber-like materials under isothermal conditions. At large strain, non-local gradient-enhanced damage model has been formulated and numerically implemented to predict the initiation and propagation of damage in rubber-like materials. The theoretical framework is based on the Internal State Variables (ISV)...
