Abstract
The Acoustic Emission (AE) technique, a non-destructive and instrumental investigation method, is herein applied to measure and check the evolution of damage in concrete and masonry structures. This method of analysis makes it possible to estimate the energy released by the monitored structure and to obtain information on the criticality of an ongoing process. Based on fractal concepts, which take into account the multiscale character of the energy dissipation in heterogeneous materials, an ad hoc energy parameter to evaluate the damage level of a structure is proposed.
