Uniaxial compression of brittle materials forms wing cracks which however cannot grow sufficiently to cause failure. Instead, they induce additional stresses subjecting some places of the sample to high tensile stresses acting normal to the compression axis. As the load increases these places seed new tensile cracks (mesocracks) parallel to the compression axis. The mesocracks then grow stably avoiding the wing cracks thus passing through places with positive average stress. This eventually causes' unstable mesocrack growth and failure. A model of this mechanism is verified against experimental data on dilatancy.
