We review the recent literature on the simulation of the structure and deformation of amorphous solids, including oxide and metallic glasses. We consider simulations at different length scale and time scale. At the nanometer scale, we review studies based on atomistic simulations, with a particular emphasis on the role of the potential energy landscape and of the temperature. At the micrometer scale, we present the different mesoscopic models of amorphous plasticity and show the relation between shear banding and the type of disorder and correlations (e.g. elastic) included in the models. At the macroscopic range, we review the different constitutive laws used in finite-element simulations. We end with a critical discussion on the opportunities and challenges offered by multiscale modeling and information transfer between scales to study amorphous plasticity.

• Deformation of metallic glasses: Recent developments in theory, simulations, and experiments (2016, unknown): “Nevertheless, experimental investigations using nanoscale probes now complement a rich set of computer simulations and theoretical analyses [12,13] to provide an emerging consensus of the phenomenology of the structural origin of mechanical response in these materials.”
• Deformation and flow of amorphous solids: Insights from elastoplastic models (2017, background): “They rely on simple assumptions to connect the microsopic phenomenology to the macroscopic behavior and therefore have a central position in the endeavor to bridge scales in the field (Rodney et al., 2011).”
• Micro-plasticity and recent insights from intermittent and small-scale plasticity (2017, background): “ instabilities of the atomic structure. Despite this caveat, such simulations have provided extremely valuable insights into what can happen at the atomic scale. A detailed overview is found in Refs. [90, 116]. The main finding of atomistic simulations is that athermal plasticity is mediated by spat”
