Mechanism of Rock Samples
Reversible Deformation under Uniaxial Stress
The phenomenon of rock samples reversible deformation under stress discussed since 1958, but the mechanism of this phenomenon has not yet been find out. Previously suppositions are not explains all the experimentally established facts. Conducted using modern load frame, strain and acoustic equipment, special complex studies have shown a direct relationship with the formation of reversible deformations with forming source of failure. The hypothesis of near-source mechanism of reversible deformations has been confirmed during special tests.
Key words: samples, rocks, reversible deformation, acoustic emission, source of failure.
