Crack Speed Calculations for Unidirectional Laminae



Based on the physical hypotheses that (a) the random properties of fracture in composite materials can be described by a nominal crack size and (b) the surplus of applied work to create new crack surfaces is converted into kinetic energy, an equation for crack speeds in orthotropic composites subjected to a uniform constant normal stress is derived. When the crack length in a composite increases and gets longer than the critical crack length, the crack speed increases asymptotically and finally reaches a limiting speed.
