The computational homogenization for modelling of large deforming fluid saturated porous media
Original language description
We have developed a model of fluid saturated porous media (FSPM) subject to large deformation. The mechanical model describes FSPM with hyperelastic skeleton and compressible viscous fluid. The dynamic behaviour is confined to approximation of the inertia effects associated with the relative fluid-solid motion so that the model is convenient for describing quasistatic loading of large-deforming porous structures. The computational algorithm is based upon a consistent incremental formulation in the Eulerian framework, such that the incremental formulation uses the updated Lagrangian approach. The formulation is based on a quasistatic perturbation of the medium described by the Biot model which is constituted by poroelastic coefficients and the permeability governing the Darcy flow. The equilibrium equation and the mass conservation are expressed in the spatial, deformed configuration. Using the material derivative with respect to a convection velocity field, a rate formulation is derived which allows to approximate the residuum function associated with the unknown configuration using the last known configuration.
