Abstract
The numerical results of 1100-aluminium extrusion tests conducted at a tool ve-locity of 36 km/h are presented. Engineering applications of the considered problem concern the use of this extrusion technology in the design of an impact energy-absorbing device. Viscous and plastic properties of the extruded materials are described on the basis of numerical simulations of a tensile test in which the Bodner-Partom material model is applied. The numerical results are compared with experimental ones.
