Abstract In the present work, an incompressible smoothed particle hydrodynamic (SPH)
method is introduced to simulate water-soil-structure interactions. In the current calculation,
the water is modelled as a Newtonian fluid. The soil is modelled in two different cases. In the
first case, the granular material is considered as a fluid where a Bingham type constitutive
model is proposed based on Mohr-Coulomb yield-stress criterion, and the viscosity is derived
from the cohesion and friction angle. In addition, the fictitious suspension layers between
water and soil depending on the concentration of soil are introduced. In the second case,
Hooke’s law introduces elastic soil.… More >
