Role of crystal lattice structure in predicting fracture toughness
Thuy Nguyen, Daniel Bonamy
We examine the atomistic scale dependence of material's resistance-to-failure by numerical simulations and analytical analysis in electrical analogs of brittle crystals. We show th…
Scaling exponents for fracture surfaces in homogenous glass and glassy ceramics
Daniel Bonamy, Laurent Ponson, Silke Prades +2
We investigate the scaling properties of post-mortem fracture surfaces in silica glass and glassy ceramics. In both cases, the 2D height-height correlation function is found to obe…
Fracture of glassy materials as detected by real-time Atomic Force Microscopy (AFM) experiments
F. Celarie, S. Prades, D. Bonamy +5
We have studied the low speed fracture regime for different glassy materials with variable but controlled length scales of heterogeneity in a carefully mastered surrounding atmosph…
Glass breaks like metals, but at the nanometer scale
F. Celarie, S. Prades, D. Bonamy +4
We report in situ Atomic Force Microscopy experiments which reveal the presence of nanoscale damage cavities ahead of a stress-corrosion crack tip in glass. Their presence might ex…
Experimental study of granular surface flows via a fast camera: a continuous description
D. Bonamy, F. Daviaud, L. Laurent
Depth averaged conservation equations are written for granular surface flows. Their application to the study of steady surface flows in a rotating drum allows to find experimentall…
Electrical conductance of a 2D packing of metallic beads under thermal perturbation
D. Bonamy, L. Laurent, Ph. Claudin +2
Electrical conductivity measurements on a 2D packing of metallic beads have been performed to study internal rearrangements in weakly pertubed granular materials. Small thermal per…
