Real-in time Ct text of the roch meso-damage propagation law

摘要

The real-in time computerized tomography (CT) test of the meso-damage propagation law of the whole rock failure process has been completed using the newest specified triaxia loading equipment corresponding to the CT machine. Theough the CT scanning, the clear CT images which in- clude the microholles (microcracks) compressed →growth→bifurcation→development→crack fracture →the rock sample failure→unloading in the different stress states were obtained.
