Experimental study on cyclic property of rocks under uniaxial compression

摘要

Systematic experimental studies of rocks under cyclic loading with lower and higher frequency at the pre- and post-peak were conducted in present paper. The macro fracture of samples, strength property, different deformation development of average strain and strain in the middle of sample, the plastic detained loops, and the development of tangent modulus during cyclic loading were analyzed in details to show the structural property of rocks.
