摘要： A bumper beam exhibiting integral attachment parts (3) acting as direct interface between the vehicle structure and the beam is provided by a novel manufacturing method where selected areas of a member (1) are subjected to reshaping along its all three main axes allowing for a new one-piece bumper beam construction integrating also energy absorbing crash box member (5).

摘要： A method is provided of determining a heat treatment to apply to a structural member so as to modify the deformation behaviour of the structural member when subjected to an applied stress. The method comprises firstly simulating the deformation behaviour of the structural member when subjected to the applied stress. The effect of at least one heat treatment upon the part of the structural member is then simulated so as to determine a heat treatment to apply to the part of the structural member so as to produce the modified deformation behaviour.
