Device testing - Import export

The basic equipment consists of an ultrasound generator, which is placed in the hold, and a receiver unit fitted with a microphone to receive the emitted ultrasound signals. It is a non-destructive method, non -invasive, can be used in all weather conditions, and can be used with cargo inside the hold.

Shape-memory alloy devices SMAD are axial restraining devices that exploit the superelastic properties of shape-memory alloys. The force-displacement curve, characterized by one or more "wedges" (sections where force remains nearly constant while displacement increases), allows SMAD to limit the maximum force transferred to the structure they are connected to. They are also characterized by a significant recentering capacity. Experimental force-displacement curve of a shape-memory alloy device. Vibrating table tests on brick walls with SMAD devices used as horizontal tie rods. SMAD devices installed at the San Francesco Basilica in Assisi.
