Keywords:fluid-solid interaction, solid-solid interaction, saturated particle layer, internal fluidization, pore water pressure, particle contact force, domain decomposition parallel computation

The computation method, which allows us to deal with the particle-scale fluid-solid and solid-solid interactions, was applied to the internal fluidization in a saturated particle layer to understand the characteristics of particle motions and physical variables of the pore fluids. With the experimentally measured results, the mechanical progress of the internal fluidization was discussed.
