Parallel Numerical Analysis on the Rheology of the Martian Ice-Rock Mixture

  • Received Date: 2017-03-21
  • The distribution and amount of ground ice on Mars is an important issue to be addressed for the future exploration of the planet. The occurrence of interstitial ice in Martian frozen ground is indicated by landforms, such as fluidized ejecta craters, softened terrain, and fretted channels. However, experimental data on the rheology of ice-rock mixture under Martian physical conditions are sparse, and the amount of ground ice that is required to produce the viscous deformation observed in Martian ice-related landforms is still unknown. In our study, we put forward a three-dimensional non-Newtonian viscous finite element model to investigate the behavior of ice-rock mixtures numeri-cally...

Abstract: The distribution and amount of ground ice on Mars is an important issue to be addressed for the future exploration of the planet. The occurrence of interstitial ice in Martian frozen ground is indicated by landforms, such as fluidized ejecta craters, softened terrain, and fretted channels. However, experimental data on the rheology of ice-rock mixture under Martian physical conditions are sparse, and the amount of ground ice that is required to produce the viscous deformation observed in Martian ice-related landforms is still unknown. In our study, we put forward a three-dimensional non-Newtonian viscous finite element model to investigate the behavior of ice-rock mixtures numeri-cally...
