Dense architectured materials are composed of building blocks of well-defined size and geometry which are quasi-rigid, but which are joined by interfaces that can sustain large deformations and channel cracks. The blocks can therefore slide, rotate, separate or interlock collectively, providing a wealth of tunable mechanisms and combinations of properties which are unattainable in monolithic materials. Interestingly, dense biological materials such as bone, teeth or mollusk shells can also be interpreted as dense architectured materials, with specific architectured and mechanisms that have been finely tuned over millions of years. We are now duplicating these structures and mechanisms from the top down, by carving weak interfaces within the bulk of hard materials such as glasses or ceramics. This architectured / bio-inspired approach leads to dense materials with unusual combinations of properties which usually conflict: High stiffness and high toughness in nacre-like glasses, hardness and flexural compliance in fish scale-inspired architectured coatings.
