Structural-temporal approach for dynamic strength characterization of rock

Abstract

Test results of rock obtained by split Hopkinson bar apparatus and his modifications. A uniform interpretation of fracture rate effects of the tested marble samples is given on the basis of the incubation time approach based on a set of fixed material constants. Time dependences of both compressive and tensile strengths are calculated using the incubation time fracture criterion. © 2015, Institute of Problems of Mechanical Engineering.
