Abstract (en)
[origin: DE19915237A1] Deformation element is made of a lithium or magnesium alloy. Independent claims are also included for: (i) a deformation element consisting of a ductile, energy absorbent metallic material of \} 2.5 g/cm<3> density, especially a lithium or magnesium alloy, the material having an absorbed impact energy of \- 33 J as measured on a notch-free specimen at room temperature; (ii) a deformation element consisting of a ductile, energy absorbent metallic material of \} 2.5 g/cm<3> density, especially a lithium or magnesium alloy, the material exhibiting a specific absorbed deformation energy of \- 5000 Nm/kg and/or an absorbed deformation energy of \- 3000 Nm as measured on cylindrical tubes of 100 mm outside diameter and 2 mm wall thickness over a 200 mm deformation path at room temperature in a quasi-static deformation test and/or a dynamic crash test; and (iii) an assembly of support elements and deformation elements as described above.
