Evaluation of soil and fluid structure interaction in blast modelling of the flying plate test
We modelled the flying plate blast scenario using ALE, based on an experimental study. Comparison of three soil models highlights variable kinematic and structural plate responses. We deduced the material parameters of prairie soil for use in the FHWA soil model. Pore pressure development and soil softening are important in accurate impulse calculation. Correlation between charge shape and pressure wave directionality leads to soil densification.
