Static–dynamic reloading degradation and brittle-to-ductile failure transition of cyclically pre-damaged sandstone: A multiscale experimental study

Rock masses in underground engineering commonly experience cyclic disturbances induced by blasting, excavation, and seismic loading, which can generate persistent internal damage and strongly affect their subsequent reloading behavior. To clarify the unified mechanism governing the static and dynamic responses of cycli...
