Fracture under body forces: An accessible test and analysis
Farhad Kamarei, Sarah Bueno De Castro, Jeffery R. Roesler +1
Fracture in large-scale structures --- from failing concrete dams to calving glaciers --- is dominated by self-weight. Yet, owing to their immense scale, directly studying when and…
Nucleation and propagation of brittle fracture as a constrained energy minimization problem
Oscar Lopez-Pamies, Farhad Kamarei, Gilles A. Francfort +1
This paper presents a macroscopic, or continuum, theory aimed at describing when, where, and why cracks nucleate and propagate in nominally elastic brittle materials under monotoni…
A Guide to Fully Characterize the Fracture Properties of Cementitious Materials from Simple Experiments
Subhrangsu Saha, Bruce J. Moore, Ben Manaugh +2
Guided by recent advances in the understanding of nucleation and propagation of fracture in elastic brittle materials, this paper proposes a suite of three simple experiments that…
Breaking Four-Point and Three-Point Bending Tests
Subhrangsu Saha, Jeffery R. Roesler, Oscar Lopez-Pamies
Since their initial standardizations in the 1930s and 1950s, the so-called four-point and three-point bending tests on unnotched beams have been embraced by practitioners as two po…
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…
Nucleation and propagation of fracture in viscoelastic elastomers: A complete phase-field theory
Farhad Kamarei, Evan Breedlove, Oscar Lopez-Pamies
This paper presents a macroscopic theory, alongside its numerical implementation, aimed at describing, explaining, and predicting the nucleation and propagation of fracture in visc…
Validating Griffith fracture propagation in the phase-field approach to fracture: The case of Mode III by means of the trousers test
F. Kamarei, E. Breedlove, O. Lopez-Pamies
At present, there is an abundance of results showing that the phase-field approach to fracture in elastic brittle materials -- when properly accounting for material strength -- des…
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…
The nonlinear elastic deformation of liquid inclusions embedded in elastomers
Oluwadara Moronkeji, Fabio Sozio, Kamalendu Ghosh +5
Elastomers filled with liquid inclusions -- as opposed to conventional solid fillers -- are a recent trend in the soft matter community because of their unique range of mechanical…
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…
The single edge notch fracture test for viscoelastic elastomers
Farhad Kamarei, Fabio Sozio, Oscar Lopez-Pamies
Making use of the Griffith criticality condition recently introduced by Shrimali and Lopez-Pamies (Extreme Mechanics Letters 58: 101944, 2023), this work presents a comprehensive a…
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…
A variational formulation of Griffith phase-field fracture with material strength
C. J. Larsen, J. E. Dolbow, O. Lopez-Pamies
In this expository Note, it is shown that the Griffith phase-field theory of fracture accounting for material strength originally introduced by Kumar, Francfort, and Lopez-Pamies (…
The revisited phase-field approach to brittle fracture: Application to indentation and notch problems
Aditya Kumar, K. Ravi-Chandar, Oscar Lopez-Pamies
In a recent contribution, Kumar, Bourdin, Francfort, and Lopez-Pamies (J. Mech. Phys. Solids 142:104027, 2020) have introduced a comprehensive macroscopic phase-field theory for th…
