| Sumario: | Title screen A study was made of the general regularities of localized plasticity development indeforming rocks. The potential usefulness of speckle photography techniques in applications toproblems of deformation and fracture in rocks was explored and circumscribed. The evolutionof localized plasticity in rocks was addressed using wave ideas. The tests were performed forthe compression samples of marble, silvinite and sandstone; the deformation occurred in thesematerials via different micromechanisms of plasticity. By the deformation, autowaves wouldform in the compression samples of rocks. The autowave propagation rates are in the range~10-5…10-4 m/s (0.3…3 km/yr), which is close to slow motion rates observed in the earth crustafter an earthquake or a rockslide. A correlation has been established between the calculatedand experimental data on the time and coordinates of fracture in rocks. Режим доступа: по договору с организацией-держателем ресурса |
