The mechanical properties of ex-situ and in-situ metallic glass matrix composites (MGMCs)
have proven to be both scientifically unique and of potentially important for practical …

Granular materials are ubiquitous in our daily lives. While they have been the subject of
intensive engineering research for centuries, in the last two decades granular matter has …

The mechanical properties of amorphous alloys have proven both scientifically unique and
of potential practical interest, although the underlying deformation physics of these materials …

We present results on a series of two-dimensional atomistic computer simulations of
amorphous systems subjected to simple shear in the athermal, quasistatic limit. The …

Concrete, the solid that forms at room temperature from mixing Portland cement with water,
sand, and aggregates, suffers from time-dependent deformation under load. This creep …

Tribology is the study of adhesion, friction, lubrication and wear of surfaces in relative
motion. It remains as important today as it was in ancient times, arising in the fields of …

Since the 1970s, theories of deformation and failure of amorphous, solidlike materials have
started with models in which stress-driven, molecular rearrangements occur at localized flow …

The character of plastic deformation in metallic glasses is investigated through instrumented
nanoindentation experiments on amorphous Pd40Ni40P20 and Mg65Cu25Gd10. Using a …

We model a sheared disordered solid using the theory of shear transformation zones (STZs).
In this mean-field continuum model the density of zones is governed by an effective …

A mesoscale model, shear transformation zone dynamics (STZ dynamics), is employed to
investigate the connections between the structure and deformation of metallic glasses. The …
