... Abstract An experimental study is conducted on sandstone under different confining and pore pressures through triaxial creep tests The creep properties of sandstone under different conditions are compared and analyzed The test results show that: in the case of same confining pressure, pore...

.... Elasticinteractionsbetweenelementsand heterogeneity of material properties lead to the emergence of a complex macroscopic behavior. In particular, the primary and tertiary creep regimes associated respectively with a degradation and increase of the rate of strain, damage event and energy release were observed in the simulations...

... and the temperature of rocks was measured. Lately, research has focused especially on the rheological properties of rocks subjected to dynamic load. Tests of rheological properties at a dynamic load were conducted both in creep regime and in relaxation regime, at various levels of average load or strain...

..., Wuhan, Hubei, 430072) ABSTRACT The paper is to research the non-linear rheological model of rock. Firstly, a new concept of potential strength is proposed. Then the creep process is divided into numerous instancys, and in every instancy, the instant potential strength can be represented by the instant...
