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 …

The virial stress is the most commonly used definition of stress in discrete particle systems.
This quantity includes two parts. The first part depends on the mass and velocity (or, in some …

The equivalence of the virial stress and Cauchy stress is reviewed using both theoretical
arguments and numerical simulations. Using thermoelasticity problems as examples, we …

Atomistic simulation is a useful method for studying material science phenomena.
Examination of the state of a simulated material and the determination of its mechanical …

Nanocrystalline metals, ie, metals in which the grain size is in the nanometer range, have a
range of technologically interesting properties including increased hardness and yield …

This book describes behavior of crystalline solids primarily via methods of modern
continuum mechanics. Emphasis is given to geometrically nonlinear descriptions, ie, finite …

In this work we calculate the local elastic moduli in a weakly polydispersed two-dimensional
Lennard-Jones glass undergoing a quasistatic shear deformation at zero temperature. The …

Strain-gradient elasticity is widely used as a suitable alternative to size-independent
classical continuum elasticity to, at least partially, capture elastic size effects at the …

The general expressions, valid for any potential, for the calculation of elastic constants
through computer simulation are given. At zero temperature, the elastic constants are found …

The human erythrocyte (red blood cell, RBC) demonstrates extraordinary ability to undergo
reversible large deformation and fluidity. Such mechanical response cannot be consistently …
