Any fracture process ultimately involves the rupture of atomic bonds. Processes at the atomic
scale therefore critically influence the toughness and overall fracture behavior of materials …

Whether a stressed material fractures by brittle cleavage or ductile rupture is determined by
its ability to convert elastic strain energy to plastic deformation through the generation and …

Atomistic simulations play a crucial role in advancing our understanding of the crack-tip
processes that take place during fracture of semi-brittle materials like α-iron. As with all …

We show a novel fracture behavior and properties of brittle materials not previously
explored. These were made possible when merging macro to micro in fracture. Our findings …

We introduce a novel ultracompact nanocapacitor of coherent phonons formed by high-
finesse interference mirrors based on atomic-scale semiconductor metamaterials. Our …

When a dynamic crack front travels through material heterogeneities, elastic waves are
emitted, which perturb the crack and change the morphology of the fracture surface. For …

Mechanical anisotropy and point defects would greatly affect the product quality while
producing silicon wafers via diamond-wire cutting. For three major orientations concerned in …

We present density functional theory based atomistic calculations predicting that slow
fracturing of silicon is possible at any chosen crack propagation speed under suitable …

Bone and other natural material exhibit a combination of strength and toughness that far
exceeds that of synthetic structural materials. Bone's toughness is a result of numerous …

Dynamic crack involves instabilities promoted by either external perturbation or intrinsic front
oscillation. In an effort to decipher fracture surface markings of brittle materials, crack …
