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…
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…
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…
