The fracture of brittle amorphous materials is an especially challenging problem, because
the way a large object shatters is intimately tied to details of cohesion at microscopic scales …

▪ Abstract Atomistic aspects of dynamic fracture in a variety of brittle crystalline, amorphous,
nanophase, and nanocomposite materials are reviewed. Molecular dynamics (MD) …

Fracture is a catastrophic process whose understanding is critical for evaluating the integrity
and sustainability of engineering materials. Here, we present a machine-learning approach …

Using a bond-based peridynamic model, we are able to reproduce various characteristics of
dynamic brittle fracture observed in experiments; crack branching, crack-path instability …

We introduce a phenomenological continuum model for the mode III dynamic fracture that is
based on the phase-field methodology used extensively to model interfacial pattern …

The peridynamic model of solid mechanics is a nonlocal theory containing a length scale. It
is based on direct interactions between points in a continuum separated from each other by …

A strategic objective of computational materials physics is the accurate description of
specific materials on length scales approaching the meso and macroscopic. We report on …

We develop a technique for simulation of the mechanics of micron-scale solid systems:
coarse-grained molecular dynamics (CGMD). It captures the important atomistic effects …

A model is presented to analyze material microstructures subjected to quasi-static and
dynamic loading. A representative volume element (RVE) composed of a set of grains is …

Architected materials typically rely on regular periodic patterns to achieve improved
mechanical properties such as stiffness or fracture toughness. Here we introduce a class of …
