Influence of dynamic disturbance on rock creep from time, space and energy aspects

In order to explore the influence of dynamic disturbance on creep behavior rock, damage evolution in rock under are reproduced with model. this model, constitutive law combined and loading condition is implemented based elastic principle Norton-Bailey equation COMSOL Multiphysics. The numerical results show that alters three aspects, i.e., time, space energy. temporal aspect, not only accelerates but also leads tensile accounting for main mode. mode mainly occurs during unloading stage disturbance, tendency transition becomes evident more disturbances. spatial may facilitate development damage, resulting unstable failure. energy causes creeping absorb release a short which can be quantified dissipation rate. residual deformation caused by exponentially related
