In order to strengthen disaster prevention control under deep resource development and space utilization, it is necessary construct a damage intrinsic model complex stress states predict the mechanical behavior of deep-rock mass cyclic loading. An indoor uniaxial loading test on sandstone was carried out in this paper. By analyzing properties energy transformation failure process, assumed that ...

In order to study the deformation and failure characteristics of rocks under different cyclic loading unloading paths, three stress path tests were conducted, acoustic emission (AE) monitoring was conducted simultaneously. The mechanical AE paths analyzed, influences on energy dissipation damage investigated. law evolution considering viscoelasticity obtained. concept ultimate its calculation m...
