In this work we continue to investigate the well-posedness for infinitesimal dislocation based gradient viscoplasticity with linear kinematic hardening. We assume an additive split of the displacement gradient into non-symmetric elastic distortion and non-symmetric plastic distortion. The thermodynamic potential is augmented with a term taking the dislocation density tensor into account. The co...

We study dynamic rupture propagation on flat faults using 2D plane strain models featuring strongly rate-weakening fault friction (in a rate-and-state framework) and off-fault Drucker–Prager viscoplasticity. Plastic deformation bounds stresses near the rupture front and limits slip velocities to ∼10 m=s, a bound expected to be independent of earthquake magnitude. As originally shown for rupture...
