Acoustic Emission/Micro-seismic monitoring of cracking of rock or rock mass is important for assessing the integrity of rock mass and to take necessary precautions in the stability analysis of underground and open pit geomechanical structures. Micro-mechanics of deformation of rock and precursors to major failure or rock bursting mechanisms can be best(More)
Fibre Bragg grating based acoustic emission measurement technique is employed to monitor crack activity in civil engineering structures and sites. The feasibility and effectiveness of using fibre optic methods for crack activity monitoring is demonstrated with three example cases (a) railway ballast breakage (b) cold crack monitoring in welding (c) crack(More)
