Energy radiation of moving cracks
arXiv:cond-mat/0110471 · doi:10.1103/PhysRevB.66.104104
Abstract
The energy radiated by moving cracks in a discrete background is analyzed. The energy flow through a given surface is expressed in terms of a generalized Poynting vector. The velocity of the crack is determined by the radiation by the crack tip. The radiation becomes more isotropic as the crack velocity approaches the instability threshold.
