The mechanism of reversible deformation phenomena in highly stressed rock samples conditions
For the first time, attention to the reversible character of linear deformations of rocks was drawn, in all probability, by T.R. Seldenrath and J. Gramberg in 1958. While searching for precursors of deformations, the reversible deformations were determined also by I.S. Tomashevskaya and Ya.N. Khamidullin (1972), who advanced the dilatancy hypothesis. In 1986, K. Tazhibaev pointed to residual stresses as the causes of the reversible deformations. However, as M.A. Guzev and V.M. Makarov stated in 2005, none of the hypotheses can explain the occurring abnormalities in a conclusive way. The present article deals with the reversible deformations investigated by a complex acoustic and deformation method, whereas the results are presented from the position of the self-balanced stresses.
Key words: sample, reversible deformation, mathematical model.
