Propagation and kinetic roughening of wave fronts in disordered lattices
Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics
The dynamics of a wave front propagating in diluted square lattices of elastic beams is analyzed. We concentrate on the propagation of the first maximum of a semi-infinite wave train. Two different limits are found for the velocity depending on the bending stiffness of the beams. If it vanishes, a one-dimensional chain model is derived for the velocity and the amplitude is found to decrease exponentially. The first maximum is localized and the average width of the wave front is always finite.doi:10.1103/physreve.56.6042 fatcat:vgx3oqpfarhd5cipwukow6atru
