We perform atomistic simulations on the fracture behavior of two typical metallic glasses,
one brittle (FeP) and the other ductile (CuZr), and show that brittle fracture in the FeP glass is …

Crack propagation is the major vehicle for material failure, but the mechanisms by which
cracks propagate remain longstanding riddles, especially for glassy materials with a long …

Molecular dynamics simulations of cavitation in a Zr 50 Cu 50 metallic glass exhibit a waiting
time dependent cavitation rate. On short time scales nucleation rates and critical cavity sizes …

To gain insight into the large toughness variability observed between metallic glasses
(MGs), we examine the origin of fracture toughness through bending experiments and …

Fracture mechanisms of metallic glasses are fundamentally different from that of crystalline
alloys. Nano-voids formation and coalescence inside shear bands were believed to be one …

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 …

Recent experiments have evidenced the existence of a ductile fracture mode at the
nanometer scale in Aluminosilicate glass. The present study is designed to check whether …

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 …

The emergence of size-dependent mechanical strength in nanosized materials is now well-
established, but no fundamental understanding of fracture toughness or flaw sensitivity in …

Quantitative understanding of the fracture toughness of metallic glasses, including the
associated ductile-to-brittle (embrittlement) transitions, is not yet available. Here, we use a …
