Modeling the mechanics of amorphous solids at different length scale and time scale

Abstract

We review the recent literature on the simulation of the structure and\ndeformation of amorphous glasses, including oxide and metallic glasses. We\nconsider simulations at different length and time scales. At the nanometer\nscale, we review studies based on atomistic simulations, with a particular\nemphasis on the role of the potential energy landscape and of the temperature.\nAt the micrometer scale, we present the different mesoscopic models of\namorphous plasticity and show the relation between shear banding and the type\nof disorder and correlations (e.g. elastic) included in the models. At the\nmacroscopic range, we review the different constitutive laws used in finite\nelement simulations. We end the review by a critical discussion on the\nopportunities and challenges offered by multiscale modeling and transfer of\ninformation between scales to study amorphous plasticity.\n
