Biomimetic designs inspired by seashells

This article explains some interesting aspects of the mechanical behaviour of seashells. Their unique brick-mortar architecture makes them tougher and stronger than their constituents. Pearly layers in seashells, also known as nacreous layers, have an order of magnitude higher toughness than most ceramics. Replication of these features of seashells in synthetic ceramics can have immediate practical applications; for example, design of lightweight, efficient and cost-effective armour.
