Applied yield stress profiles in regional models. Yield stress envelopes for the different experiments with either depth-constant (Δ σ y =0), depth-dependent (σ y,const=) or composite (σ y,const, Δ σ y ≠0) yield stresses. The transition between brittle (i.e. depth-dependent) and ductile (i.e. depth-constant) yielding is set to occur in the middle of the plate, at 50 km depth
