The upper portion of the Earth's crust contains a hierarchy of structural features that span a wide range of length scales. The evolution of these features in response to dynamic and quasistatic loading remains a challenging problems in geophysics and geomechanics. The problem is further complicated by the highly nonlinear nature of friction and deformation at microscale. Faulting, brittle to ductile transition, strain localization and comminution are some of the important mechanisms contributing to mutiscale damage complexity in solids. This minisymposium welcomes contributions in the broad field of damage modeling in quasi-brittle solids with a special focus on applications related to rock mechanics and earthquake physics. Topics include but not limited to: 1) Modeling of breakage and healing mechanisms in granular materials, 2) Modeling of wear and rock comminution, 3) Mechanisms of strain localization under dynamic loading, 4) Conditions for Brittle to ductile transition in rocks and gouge, and 5) Dynamic rupture simulation on frictional surfaces.
