Paper Abstract

The characterization of materials used in civil constructions is needed and for this purpose many parameters can be obtained from experimental tests. In the last years optical interferometric techniques have acquired more and more importance in laboratory tests and can be proposed as alternative or complementary means to classical techniques. On the basis of previous calibration tests, in the paper the authors describe the application of ESPI method to the determination of the crack tip position and of the strain field surrounding the crack that propagates in a specimen of clay material.
