Dynamic crack propagation with a variational phase-field model: limiting speed, crack branching and velocity-toughening mechanisms (2017, methodology): “cohesive elements [73] and a non-local integral damage model [67].”
Simulations of instability in dynamic fracture by the cracking particles method (2009, unknown): “[8] have proposed a rate-dependent phenomenological model that accounts for effects of the instabilities on crack speed, but does not explicitly model the crack branches.”
The cohesive element approach to dynamic fragmentation: the question of energy convergence (2007, methodology): “Rate-dependent cohesive laws, for which Gc becomes an increasing function of strain rate, are promising in this regard [37, 47, 48].”
Quasi-static and dynamic fracture behaviour of rock materials: phenomena and mechanisms (2014, background): “Zhou et al. (2005) also explained that the notable increase of energy dissipation in polymethylmethacrylate with increasing crack speed is governed by the interaction of multiple microcracks around the crack tip zone.”

An adaptive spacetime discontinuous Galerkin method for cohesive models of elastodynamic fracture (2010, background): “Rate-dependent and thermomechanical cohesive models [35, 36] provide more accurate descriptions of certain fracture processes where high strain rates accompanied by significant temperature increases have been observed [38, 65].”
