Strength and Deformability of Brittle Polycrystalline Materials in Triaxial Stress-State State

Аннотация

The strength and deformability of brittle polycristalline materials (rock, cement, gypsum) in triaxial stress-strain state are analyzed. It is shown that the strength of such materials increases. The subcritical and postcritical stress-strain curves for polycristalline materials are presented.
