The laboratory of the Mechanical Testing is equipped with cutting edge machines and measuring devices offering the capability of a wide spectrum mechanical tests under static and dynamic loading conditions and variable temperatures.
Characteristic examples of such testing techniques are the following:
Low and high temperature tensile testing
Low and high temperature three- and four-point bend testing
Static and Quasi-Static Compression testing
Sheet Formability testing
CTOD Fracture Toughness testing
Formability testing equipment is available, including Erichsen doming and cup-drawing machines for the testing of anisotropic behaviour of rolled sheets.
The laboratory team has also expertise in the study of machinability of conventional and eco-friendly alloys and participates to the investigation of mechanical properties of components produced using advanced manufacturing technologies.
Its research activities also cover areas of failure analysis and root cause investigation of materials and machine components.
