Energy radiation of moving cracks
S. Fratini, O. Pla, P. Gonzalez +2
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 veloc…

Straight cracks in dynamic brittle fracture
O. Pla, F. Guinea, E. Louis +2
We study the dynamics of cracks in brittle materials when the velocity of the crack is comparable to the sound velocity by means of lattice simulations. Inertial and damped dynamic…
