Published in 2019 at "Pure and Applied Geophysics"

DOI: 10.1007/s00024-019-02207-2

Abstract: Modeling dynamic and static responses of an elastic medium often employs different numerical schemes. By introducing damping into the system, we show how the widely used time-marching staggered finite difference (FD) approach in solving elastodynamic… read more here.
