Creature feature: Twisting cracks impart superhero toughness to animals
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 after the phenomenon. The work was performed by a team of researchers at Purdue University in collaboration with University of California, Riverside.
