Infinite element simulation of catastrophe induced by evolution of rock microfracturing damage

Based on the phenomena of damage localization in rock deformation, the infinite element simulation on damage evolution of two-dimensional network system shows that the stochastic disorder of rock microfracturing progressively develops into localized order in damage evolution into macrofacturing . The time sequence and spacial distribution of acoustic emission generated by rock failure are also simulated by using the hypothesis of the accordance between rock microfracturing and acoustic emission.
