Bridging perturbation and variational approaches in brittle fracture
Serafim Egorov, Antoine Sanner, Jean Sulem +2
We present a variational reduced-order model for three-dimensional coplanar propagation of sharp cracks in heterogeneous perfectly brittle solids under mixed-mode I+II+III loading.…
Size effects in the toughening of brittle materials by heterogeneities: a non-linear analysis of front deformations
Mathias Lebihain, Manish Vasoya, Véronique Lazarus
Traditional computational approaches in simulating crack propagation in perfectly brittle materials rely on the estimate of stress intensity factors along the rupture front. This p…
Dynamic crack front deformations in cohesive materials
Thibault Roch, Mathias Lebihain, Jean-François Molinari
Crack fronts deform due to heterogeneities, and inspecting these deformations can reveal local variations of material properties, and help predict out of plane damage. Current mode…
Quasi-static crack front deformations in cohesive materials
Mathias Lebihain, Thibault Roch, Jean-François Molinari
When a crack interacts with material heterogeneities, its front distorts and adopts complex tortuous configurations that are reminiscent of the energy barriers encountered during c…
Earthquake Nucleation along Faults with Heterogeneous Weakening Rate
Mathias Lebihain, Thibault Roch, Marie Violay +1
The transition from quasi-static slip growth to dynamic rupture propagation constitutes one possible scenario to describe earthquake nucleation. If this transition is rather well u…
