Mathematical modeling of two problems of wave dynamics in heterogeneous media

Interaction of debris with a solid obstacle: Numerical analysis

“…Federov et al [13] analyse two problems, where the first one is the interaction of a shock wave with a layer. The results are compared with experimental observations.…”

Interaction of a normally incident shock wave with a porous material layer on a solid wall

“…The model of two compressible isothermal media with identical phase pressures and velocities was used in [5,6] to solve the problem of spreading of a compressed stratified medium. The studies described in those papers were focused on investigating the decay of a discontinuity formed by breakdown of a diaphragm between the high-pressure chamber containing the stratified layer of the substance (sand or Plexiglas) at the initial time and the low-pressure chamber filled by the gas.…”
