Micro Abstract:
In the presentation, using a combination of analytical micromechanics models and direct numerical simulations, the effective diffusivity of microcracked porous REVs for various isotropic and anisotropic microcrack configurations are investigated. Furthermore, the level of applied external loading on the effective diffusivity of a fracturing material is simulated by an element-erosion based mesoscale pixel-FE model for fracture coupled with diffusion using selected numerical experiments.
