Permanent shear localization in dense disordered materials due to microscopic inertia

摘要: In this work we develop a theoretical framework for the localization of flow in steadily flowing regime sheared disordered solids with inertial dynamics on microscopic scale. To aim perform rheology studies at fixed shear rate 3D model dense solid. Our particle based simulations reveal existence heterogeneous shear-profiles stationary under homogeneous driving conditions. rationalize result, propose continuum that couples local to evolution kinetic temperature field. A linear stability analysis theory predicts minimum system size necessary instability develop. This prediction as well velocity profiles obtained from are good agreement results simulations.
