LABORATORIES

Instabilities Lab
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.
