Summary[edit]

Description
English: Supplementary Movie 4 Formation of nanocracks and their interaction with main crack in the conch shell. The advancing main crack was blocked frequently by the slanted TBs. While the main crack is trapped at the TBs for a while, nanocracks (marked by yellow arrows in the movie) were nucleated ahead of the main crack. The main crack propagated through repeated deflection and coalescence with the nanocracks. This observation inspired coarse-grained simulations to reveal the optimum spacing and size of nanocracks (Supplementary Method 5). The observed crack pattern is very close to one that yields the highest fracture toughness in the simulation (Supplementary Discussion 7).
