Abalone: Toughening Mechanisms
•Viscoplastic deformation of organic glue layer
•Sliding occurs between tiles before tensile failure.
Tile Sliding
Microscale:
Aragonite Tiles
•Individual polygonal
aragonite tiles in brick and
mortar structure
•0.5µm x 10µm tiles held together
with 20-30nm thick layer of organic glue
