The three-dimensional governing equations of the flow field that is developed when
an elasto-plastic exible porous medium, capable of undergoing extremely large
deformations, is struck head-on by a shock wave, are developed using a multi-phase
approach. The one-dimensional version of these equations is solved numerically
using an arbitrary Lagrangian–Eulerian (ALE) based numerical code. The numerical
predictions are compared qualitatively to experimental results from various sources
and good agreement is obtained. This study complements our earlier study in which
we developed and solved, using a total variation diminishing (TVD) based numerical
code, the governing equations of the flow field that is developed when an elastic
rigid porous medium, capable of undergoing only very small deformations, is struck
head-on by a shock wave.
