Stochastic fatigue damage in viscoelastic materials using probabilistic pseudo J-integral Paris' law
TL;DR: In this paper, a pseudo J-integral Paris' law model and probability theory are combined to establish a stochastic fatigue damage model for viscoelastic materials, and the model can track the entire fatigue damage process of viscous materials by coupling the variability with the fatigue mechanism.

Correspondence principles and a generalized J integral for large deformation and fracture analysis of viscoelastic media
TL;DR: In this paper, a quasi-static deformation and fracture analysis for nonlinear viscoelastic media and sample applications are given. But the authors focus on predicting mechanical work available at the crack tip for initiation and continuation of growth.

Energy-Derived, Damage-Based Failure Criterion for Fatigue Testing:
TL;DR: In this paper, a method is presented for examining dissipated energy to select a consistent level of material behavior that is indicative of the damage accumulation in the mixture, showing the similarity between the constant stress and constant strain modes of testing and providing the potential for unifying the now phenomenological description of fatigue.
