Figure 4.21b. Propagation simulations for two 25-m-long anticrack bands approaching
each other along parallel paths (orthogonal to the maximum remote compressive stress) at
a normalized differential stress of 0.25 and initial spacing intervals of 2.5 cm (top), 25 cm
(middle) and 2.5 m (bottom). Black lines indicate starting configurations, colored lines
indicate simulated paths, all dimensions in meters.
