THE study of fracture is an old topic1, but only recently has an understanding begun to emerge of crack formation, propagation and morphology (which is often fractal) 2–8. When a brittle material such as glass is broken under tensile stress9, the cracks have a complicated morphology10. Fineberg et al.11 showed that this process may be caused by a dynamic instability, whereby the speed of crack propagation increases until it approaches the speed of sound: at this point, complex structures appear… CONTINUE READING
