While there exists a unified theoretical framework–Linear Elastic Fracture Mechanics–to
describe the failure of homogeneous materials, understanding and modeling the …

Stress enhancement in the vicinity of brittle cracks makes the macro-scale failure properties
extremely sensitive to the micro-scale material disorder. Therefore,(i) fracturing systems …

We investigate the scaling properties of postmortem fracture surfaces in silica glass and
glassy ceramics. In both cases, the 2D height-height correlation function is found to obey …

We explore the possibility of engineering the crack path by controlling a material's
microstructure in order to increase its crack growth resistance. Attention is confined to a …

In an effort to investigate the link between failure mechanisms and the geometry of fractures
of compacted grains materials, a detailed statistical analysis of the surfaces of fractured …

Using a multi-resolution technique, we analyze large in-plane fracture fronts moving slowly
between two sintered Plexiglas plates. We find that the roughness of the front exhibits two …

Material failure often gives rise to strong fluctuations that reflect on the rough trajectory
followed by cracks and on their intermittent dynamics. Deciphering these fluctuations is a …

The fracture surfaces of a Zr-based bulk metallic glass exhibit exotic multi-affine isotropic
scaling properties. The study of the mismatch between the two facing fracture surfaces as a …

We show that a length scale ξ can be extracted from the spatial correlations of the “steep
cliffs” that appear on a fracture surface. Above ξ, the slope amplitudes are uncorrelated and …

We investigate the influence of stress conditions during fracture formation on the geometry
and roughness of fracture surfaces. Rough fracture surfaces have been generated in …
