18. If the thresholds vary independently, fine tuning becomes necessary to produce nontrivial steady-state patterns [8]; no such tuning is evident in nature.
19. This is a trick to introduce the effect of thickness without incurring a demanding three-dimensional simulation.
20. Partially and fully periodic boundary conditions are also considered. They lead to similar patterns with the same fragment-area statistics.
21. α specifies the fraction of the force components distributed to neighbors in a slip. Note that without external driving all force components are strictly conserved locally during slipping and cracking, for all s.
22. Smaller initial strain leads to more diffusive cracks. Generally, typical straight-crack length increases with s.
