000014241 520__ $$2eng$$aThin steel tubes are characterized by a case-hardened surface of 15% of tubes outer surface for a certain depth with different geometrical shapes via carbonitriding process. The patented idea [1] aims to enhance the resistance of the tubes against external loadings. Different shapes of the treated surface are proposed: 4 different ring-shape configurations (2, 3, 4 and 5 rings), a shape with 3 uniformly distributed vertical strips parallel to the axis of the tube and three helically treated cases with tilt angles of 30°, 45° and 60°. These tubes are tested via a dynamic drop mass bench of a maximum impact velocity of 9.5 m/s showing their behavior during dynamic plastic buckling. The obtained results reveal that the 4-ring case provides the best energy absorption enhancement of 65% compared to non- treated tube.
