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…
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…
Effect of the porosity on the fracture surface roughness of sintered materials: From anisotropic to isotropic self-affine scaling
Tristan Cambonie, Jonathan Bares, Lamine Hattali +3
To unravel how the microstructure affects the fracture surface roughness in heterogeneous brittle solids like rocks or ceramics, we characterized the roughness statistics of post-m…
