On the effects of material strength in dynamic fracture: A phase-field study
Yangyuanchen Liu, Oscar Lopez-Pamies, John E. Dolbow
Over the past seven years, full-field analyses of a wide range of classical as well as modern quasi-static fracture experiments on nominally elastic brittle materials -- ranging fr…

Nucleation of fracture: The first-octant evidence against classical variational phase-field models
Farhad Kamarei, John E. Dolbow, Oscar Lopez-Pamies
As a companion work to [1], this Note presents a series of simple formulae and explicit results that illustrate and highlight why classical variational phase-field models cannot po…

Classical variational phase-field models cannot predict fracture nucleation
Oscar Lopez-Pamies, John E. Dolbow, Gilles A. Francfort +1
Notwithstanding the evidence against them, classical variational phase-field models continue to be used and pursued in an attempt to describe fracture nucleation in elastic brittle…
