Fracture Process Characterization by Acoustic Emission Signal Components

Abstract:

The aim of this work is to develop a procedure to follow the evolution of micro and macro-crack in unreinforced and reinforced masonry walls by means of Acoustic Emission signal analysis. In particular the main goal of this experimental work want to be the definition of a characteristic signal parameter able to represents the evolution of the fracture dimension in the masonry walls during the fracture process. To this end laboratory tests were carried out at the Non-Destructive Testing Laboratory of the Politecnico di Torino.
