Abstract
The hydraulic fracturing of shale, as well as the fracturing of concrete due to the alkali-silica reaction (ASR), require some interesting generalizations of Biot concept of two-phase medium. In both, the fracturing due to pore pressure if the salient physical phenomenon. The lecture explains how the concept of a three-phase medium - solid-percolating nanopores-hydraulic cracks - makes it possible to predict the lateral branching of hydraulic cracks, provided that the body forces due to gradients of pressure in nanopores are included. Some similar phenomena exist in the alkali-silica reaction (ASR) as affected by ASR gel diffusion and pore water diffusion and are important in assessing the structural damage due to ASR.
