WEST LAFAYETTE, Ind. – Super-resilient materials found in the animal kingdom owe their strength and toughness to a design strategy that causes cracks to follow the twisting pattern of fibers, preventing catastrophic failure. Researchers in a recent series of papers have documented this behavior in precise detail and also are creating new composite materials modeled
New research findings revealing the structure of a sea creature”s impact-resistant appendage are inspiring development of advanced materials for possible applications in body armor, helmets and components for buildings and cars. The “dactyl club” can reach an acceleration of 10,000 g, unleashing a barrage of ferocious impacts with the speed of a .22 caliber bullet.
