Cino Viggiani’s research involves experimental investigations as well as theoretical and numerical modeling of the behavior of geomaterials, including localized failure and hydro-mechanical coupling effects. Applications are especially concerned with petroleum industry, mining, environmental engineering and civil engineering. On the experimental side, he has been using quite a range of soils and rock testing apparatus, including plane strain compression devices for soils and rocks equipped with an ultrasonic tomography / Acoustic Emission system, and a generalized shear apparatus with principal stress rotation. Advanced methods such as Digital Image Correlation and x-ray tomography have been developed, and they are applied to experimentally detect the onset of localized failure.
