The characteristic energy length scale
describes the size of the region from which energy flows to a rapidly moving
crack. If material properties change within the characteristic energy length scale, local wave speeds can dominate crack dynamics. This can lead to
supersonic fracture Supersonic fractures are fractures where the fracture propagation velocity is higher than the speed of sound in the material. This phenomenon was first discovered by scientists from the Max Planck Institute for Metals Research in Stuttgart (Markus ...
