Fig. 5

Evolution of shear stress and slip behaviors for L (red) and S (blue), where a \(w_{0} = 0.2\,{\text{m}}\), b \(w_{0} = 0.6\,{\text{m}}\), and c \(w_{0} = 1.0\,{\text{m}}\). Plots of temporal changes in shear stress, total slip, slip deficit, and slip rate are shown for each case. Stress values are extracted from the center of each patch, while the slip quantities are averaged across each patch. The times \(T_{1}\) and \(T_{2}\) are indicated by broken lines when the shear stress has a peak at either of two patches (L or S) just before the weakening process, and the corresponding spatial distributions of slip deficit and shear stress are illustrated in the following figures
