Rapid ductile strain localization due to thermal runaway

Abstract:Thermal runaway is a ductile localization mechanism that has been linked
to deep-focus earthquakes and pseudotachylyte formation. In this study,
we investigate the dynamics of this process using one-dimensional,
numerical models of simple shear deformation. The models employ a
visco-elastic rheology where viscous creep is accommodated with a
composite rheology encompassing diffusion and dislocation creep as well
as low-temperature plasticity. To solve the nonlinear system of
differential equations governing th… Show more
