Crack-Tip Opening as a Probe for Length-Scale Separation in Geometrically Nonlinear Solids
Raúl Lazo-Molina, Mokhtar Adda-Bedia, Mohit Pundir +2
Soft elastic solids are highly deformable materials where fracture is driven by the complex coupling of geometric and material nonlinearities. While geometric nonlinearity (GNL) ar…
Self-focusing of helicity drives finite-time singularities in inviscid flows
Mokhtar Adda-Bedia, Sergio Rica
This paper deals with the longstanding quest of the possible existence of finite-time singularities in the equations governing the dynamics of inviscid fluids, namely, Euler equati…
Laddering of a knitted fabric: a topology-induced failure
Antoine Faulconnier, Laura Michel, Mokhtar Adda-Bedia +2
Laddering is the propagation of a topological defect in an everyday-life material: weft knitted fabrics, following a broken thread or a dropped stitch. What is a minor frustration…
Dual Role for Heterogeneity in Dynamic Fracture
Itamar Kolvin, Mokhtar Adda-Bedia
We approach the problem of heterogeneous dynamic fracture by considering spatiotemporal perturbations to planar crack fronts. Front propagation is governed by local energy balance…
A comprehensive study of nonlinear perturbations in the dynamics of planar crack fronts
Itamar Kolvin, Mokhtar Adda-Bedia
The interaction of crack fronts with asperities is central to the criteria of fracture in heterogeneous materials and for predicting fracture surface formation. It is known how dyn…
Curved crack paths are predicted by elastic-charges
Oran Szachter, Emmanuel Siefert, Mokhtar Adda-Bedia +2
Predicting crack trajectories in brittle solids remains an open challenge in fracture mechanics due to the non-local nature of crack propagation and the way cracks modify their sur…
