Quantitative evaluation of toughening mechanisms in abalone nacre

Tensile and fracture tests for dried nacre were carried out. Dried nacre fractured in a brittle fashion, but its toughness perpendicular to the plane of the plate was 10 times greater than that of natural CaCO3. A simple model in which plates interlock was proposed based on the observations of fract...
