Abstract
A novel technique for detecting crack formation and propagation, based upon electric emission, is described. It is shown that a correlation between electric emission and fracture exists for glass, ceramics and concrete. Experiments on crack detection in glass slabs are performed at quasistatic and dynamic loadings, and the results are discussed.
