Abstract

The paper presents the results of Digital Image Correlation (DIC) method applied to plane strain tests carried out on specimens of fissured clays from the south of Italy. Information about physical properties and Fissuring IDentity of the clays are reported together with an outline of the global behaviourial framework of the fissured clay Represententative Element Volume (REV). DIC has been used to explain some discrepancies found in the global shearing behaviour of some specimens which did not fit the framework. DIC revealed the sources of such discrepancies, which made these specimens much smaller than the REV.
