Abstract

The motive of this study is the need of scientific teams working for restoration projects of masterpieces of classical Greek antiquity to accurately describe the mechanical response of complexes made of building stones and reinforcing metallic elements. The study was presented during a special session, devoted to the memory of late Professor Pericles S. Theocaris, organized in the frame of the ‘1st International Conference of the Greek Society of Experimental Mechanics of Materials’, It is part of a wider project, the aim of which is, among others, to assess the efficiency of structural health monitoring tools in predicting upcoming failure. It is proven that the time evolution of the outcomes of both the ‘Acoustic Emissions’ and the ‘Pressure Stimulated Currents’ techniques exhibit characteristic changes that could be considered as warnings that the system studied enters to its ‘critical stage’.
