Modeling Defamations on a Molcular Dynatnics-Shnulated War-System

Abstract

Results are reported from molecular dye tunics computer simulations for metallic glasses and glass-forming melts under external shear deformations or reduced dimensions. The simulations provide rather rmique possibilities to study on the atomic level modifications of the amorphous state of matter under external perturbations. Modeling constant-shear-stress deformations makes visible details of the atontistic mechanisms of plastic deformations of the glasses. Constant-strain-rate processes reveal a deformation induced change of the amorphous structure into a state of easy deformabilty. This latter state here is ascribed to the interior of the shear bands observed experimentally under ambient temperatures. From the simulations, its properties are characterised in some detail
