| Abstract |
The article contains an analysis of the kinetics of brittle fracture processes during compression of a two-scale porous medium, in which a larger scale is associated with a system of holes. This work is a continuation of studies of fracture structures during compression. Within the framework of the project, experiments were carried out on samples of porous brittle model material (gypsum) containing a number of holes of different orientations with respect to the compression axis. They showed that fracture in the vicinity of holes in such materials under compression can develop both by initiating normal fracture cracks and by localizing compaction. In a model situation with a system of holes, the choice of the mechanism for the formation of local foci of destruction depends on the orientation of the system of holes relative to the compression axis. To interpret the experimental results, the stress state of the loaded system was calculated. A brief overview of the effects of local compaction under compression is given. |
