Abstract
By means of a dynamic simulation technique developed by the authors and based upon the Monte Carlo method, we investigate the response of two-dimensional Lennard-Jones lattice systems to dynamic uniaxial strain paths that are either fast or slow with respect to a lattice equilibration time. The simulation of lattice response to various compression-release cycles indicates a dependence of the degree of sustained lattice damage (i.e., dislocations and defects) on the rate and maximum amplitude of applied strain. Specifically, greater lattice damage is predicted whenever the lattice is subjected to a fast-loading process and/or higher maximum strain amplitude as compared to that induced by a slow-loading process and/or lower maximum strain amplitude.
