摘要
It is established experimentally that the incremental strain sign-change effect is observed in preliminarily damaged rock samples in the pre-failure zone under compression. The theory of continuous phase transition is employed to study this effect. The governing equation and its solution are derived. The numerical results obtained prove that this approach is good for adequate description of the sign-change effect for strain increments in rock samples under compression.
