Stochastic Modeling of Anisotropic Strength Surfaces from Atomistic Simulations
Alexander Bonacci, John Dolbow, Johann Guilleminot
This work develops a unified framework for inferring, representing, and statistically characterizing an anisotropic strength surface directly from molecular dynamics data. Large-sc…
A complete phase-field fracture model for brittle materials subjected to thermal shocks
Bo Zeng, John E. Dolbow
Brittle materials subjected to thermal shocks experience strong temperature gradients that in turn give rise to mechanical stresses that can be large enough to induce fracture. Thi…
Nine circles of elastic brittle fracture: A series of challenge problems to assess fracture models
Farhad Kamarei, Bo Zheng, John E. Dolbow +1
Since the turn of the millennium, capitalizing on modern advances in mathematics and computation, a slew of computational models have been proposed in the literature with the objec…
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…
A Griffith description of fracture for non-monotonic loading with application to fatigue
Subhrangsu Saha, John E. Dolbow, Oscar Lopez-Pamies
With the fundamental objective of establishing the universality of the Griffith energy competition to describe the growth of large cracks in solids \emph{not} just under monotonic…
