Abstract

The paper shows the preliminary results of uniaxial tension tests on a pearliticDuctile Cast Iron (DCI) by using the Acoustic Emission (AE) technique as wellas the Scanning Electron Microscope (SEM) analysis. The experimental testsdemonstrate the damage initiation and evolution occurring within the graphitenodules produce AE activity. The evaluation of the Shannon Entropy of theAE data is found to promising for the assessment of DCIs.
