Embedded-atom potentials are a useful supplement to pair potentials in the modelling of defects and metal plasticity. Here we emphasize the steady isothermal shear deformation of two-dimensional models made up of many interacting grains. The embedded-atom-plus-pairs potential can provide very...

Macroscopic continuum simulations can be based on an unstructured moving spatial grid made up of “smooth particles”. The smooth particles’ equations of motion include interpolated values of the macroscopic stress gradient at each particle’s position. Microscopic solid-state simulations...

Academic freedom, combined with generous travel grants and tax-supported computing, made possible my 35 years' study of many-body problems. Here I first review some of the many high points of those years. I then describe recent work - with Harald Posch, Oyeon Kum, my wife Carol, Siegfried Hess,...

The smooth-particle weighting functions used in numerical solutions of the thermomechanical continuum equations can be interpreted as weak pair potentials from the standpoint of statistical physics. We examine both equilibrium and nonequilibrium thermomechanical properties of many-body systems...

Equilibrium molecular dynamics has been generalized to simulate nonequilibrium systems by adding sources of thermodynamic heat and work. This generalization incorporates microscopic mechanical definitions of macroscopic thermodynamic and hydrodynamic variables, such as temperature and stress,...
