In this paper, the cyclic constitutive equations were proposed to describe the constitutive
behavior of cyclic loading and unloading. Firstly, a coupled damage variable was derived …

The investigation of rock damage behaviour is an important requirement for ensuring
stability control and safety prediction in rock engineering. In this study, based on the linear …

For rock engineering in cold regions, rock is often subjected to coupled fatigue conditions of
freeze-thaw (FT) and stress disturbance. Rock fracture evolution and energy mechanism …

To obtain the precise calculation method for the peak energy density and energy evolution
properties of rocks subjected to uniaxial compression (UC) before the post-peak stage …

To investigate the effects of the pre-existing single crack angle on the mechanical behaviors
and energy storage characteristics of red sandstone, a series of uniaxial compression and …

To study the creep behavior of salt rock under long-period cyclic loading, uniaxial long-
period cyclic load creep tests on salt rock specimens under different maximum cycling …

A true triaxial test system was used to study the mechanical and damage characteristics of
coal under tiered cyclic maximum principal stress (σ 1), intermediate principal stress (σ 2) …

Compared to intact coal, tectonic coal exhibits unique characteristics. The deformation
behaviours under cyclic loading with different confining pressures and loading rates are …

Because of periodic disturbance during coal seam excavation and support, the surrounding
rock is subjected to cyclic unloading-reloading. To study the effect of pressure-relief on coal …

To exam the anisotropic deformation and energy evolution characteristics of interbedded
marble, cylindrical marble samples cored along angles of 0°, 30°, 60°, and 90° with respect …
