$Downdip component of strain rate tensor and resolved stress difference from the numerical model, focusing on features within the plate/slab. The resolved stress difference is defined as ($\sigma_{s} - \sigma_{z}$), where $\hat{s}$, and $\hat{z}$ are unit vectors in the downdip and slab normal directions. The fields show, for example, shortening/extension in the downdip direction. Stress profiles at four locations are shown. The blue line ($x_0$) is the first zero crossing based on analysis of the flexural component of the topography. The black line is the location of maximum bending moment.$
