Laboratories

Laboratory for Physical Modeling of Structures and Photoelasticity
The aim of the lab is the investigation of the behaviour of materials and structures, subject to quasi-static and dynamic loadings, working on small-size models invented to capture the most important mechanical aspects. We use photoelasticity, high-speed cameras, miniaturized accelerometers, with three testing machines and a linear actuator. In addition to teaching models of frames and truss structures, we have tested models of masonry and voussoirs arches, elastic structures in conditions of buckling or flutter instability, material reinforced through thin inclusions, granular materials, and forming of metallic and ceramic powders.
