Multiscale FE simulation of diffusion-deformation processes in homogenized dual-porous media
Original language description
The paper deals with a model of the homogenized fluid saturated porous material which recently was proposed by the authors. The model was obtained using the asymptotic analysis of the Biot type medium with the dual porosity. The homogenized macroscopic model is featured by the fading memory effects arising from the microflow in the dual porosity. We derive the steady state formulations and discuss several topics related to the numerical implementation of the model, namely the solution procedure of the discretized microscopic problems, evaluation of the homogenized coefficients and an approximation of the convolution integrals of the macroscopic model, so that the fading memory effects are computationally tractable. Numerical examples are presented to illustrate the approximation schemes discussed in the paper. All computations were performed using the in-house developed finite element code SfePy allowing the multiscale simulations. Besides various potential engineering applications, th
