Beyond linear stability: Heterogeneity-induced fingering of crack fronts
Manish Vasoya, Laurent Ponson, Veronique Lazarus
We investigate the stability of elastic interfaces beyond the linear regime by considering penny-shaped crack fronts propagating through toughness heterogeneities. Using fracture m…
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…
Role of particle aggregation on the structure of dried colloidal silica layers
Arnaud Lesaine, Daniel Bonamy, Cindy Rountree +3
The process of colloidal drying gives way to particle self-assembly in numerous elds including photonics or biotechnology. Yet, the mechanisms and conditions driving the nal partic…
Highly porous layers of silica nano-spheres sintered by drying: Scaling up of the elastic properties from the beads to the macroscopic mechanical properties
Arnaud Lesaine, Daniel Bonamy, Georges Gauthier +2
Layers obtained by drying a colloidal dispersion of silica spheres are found to be a good benchmark to test the elastic behaviour of porous media, in the challenging case of high p…
Role of evaporation rate on the particle organization and crack patterns obtained by drying a colloidal layer
Keyvan Piroird, Véronique Lazarus, Georges Gauthier +3
-- A scientific hurdle in manufacturing solid films by drying colloidal layers is preventing them from fracturing. This paper examines how the drying rate of colloidal liquids infl…
Crack Front Segmentation and Facet Coarsening in Mixed-Mode Fracture
Chih-Hung Chen, Tristan Cambonie, Veronique Lazarus +3
A planar crack generically segments into an array of "daughter cracks" shaped as tilted facets when loaded with both a tensile stress normal to the crack plane (mode I) and a shear…
