KW - Lattice Boltzmann Method, elastic solids, Poisson ratio.
AB - <p style="text-align: justify;">We present a new lattice Boltzmann formulation for elastic solids and analyse
the issue of conservation laws for solids. This new formulation allows tunable
Poisson ratio. As a first benchmark problem, we consider an elastic wave propagating
in an infinite homogeneous medium with point force and point dipole Ricker wavelet
as the source. The method is successful in simulating behavior of elastic wave motion
as a function of Poisson ratio.</p>
