WebThe fracture process zone in granite: evidence and effect. J.F. Labuz;S.P. Shah;C.H. Dowding. International Journal of Rock Mechanics and Mining Sciences (1987) 167 Citations Measurement of the intrinsic process zone in rock using acoustic emission. W. K. Zietlow;Joseph F Labuz. WebThe process of localization of cracks and movement of the fracture process zone was studied using acoustic-emission techniques. The rate of acoustic-emission events and sources of acoustic-emission activity were studied for plain-mortar and model-concrete specimens loaded in direct tension.
