A Lattice Boltzmann Model for Wave and Fracture phenomena
Bastien Chopard, Pascal Luthi, Stefan Marconi
Abstract
We show that the lattice Boltzmann formalism can be used to describe wave propagation in a heterogeneous media, as well as solid-body-like systems and fracture propagation. Several fundamental properties of real fractures (such as propagation speed and transition between rough and smooth crack surfaces) are well captured by our approach.
