Abstract

Degradation processes of stressed solid materials was investigated by newly developed speckle interferometry. Sequence of speckle correlation fringes were obtained by subtracting couples of interfering speckle patterns successively acquired. The behavior of plastic deformation and fracture were observed on a video monitor as moving fringe patterns of in-plane deformation components. In experiments of a specimen of carbon steel S45C, we observed a characteristic white band which can be interpreted as a Luder's band sweeping over the specimen in the yielding state of the loading test. In experiments of an aluminum alloy specimen, complicated movement of a white and was found corresponding to load serration.
