‘Function After Failure’ in Bone Translates to Engineering Strategy
When most things break, they fall apart and lose their mechanical function. But cancellous bone, found near joints and in the vertebrae, is just the opposite. It has a relatively spongy outer surface and more a brittle interior, giving it what’s known as material heterogeneity. Researchers at Cornell have found that this property allows the bone to do something better than most man-made materials—bounce back after it breaks.
