This thesis presents an experimental and numerical investigation on the novel origami-patterned tube which is recognised as a promising energy absorption device. Its peculiar buckling mode leads to high performances in terms of specific energy absorption (SEA) and crushing force efficiency (CFE). The mode is triggered by prefolding a polygonal tube following an origami pattern, which is designed to act as geometric imperfection and mode inducer, in order flatten the buckling force peak and to trigger a predictable and efficient “diamond crushing mode”. The current work represents the first step in evaluating a potential application of origami tubes as crashworthy components on a Personal Air Vehicle, currently under development at the hosting university.
