Abstract: The reinforcement member includes a body made of a press hardened steel having a tensile strength greater or equal to 1200 MPa. The body is coated with a zinc-based coating or with an aluminum-based coating and extends along a main direction. The reinforcement member also includes at least one tab extending from the body along a transversal direction forming a non-zero angle with the main direction. The bend between the body and the tab defines an intrados and an extrados. The tab is made of a cold bent part of the body, and the elongation of the extrados is between 10% and 25%.

Abstract: A design and a production method of a front floor reinforcement structure 1 for a vehicle 3 having a battery pack 5 in the tunnel 7 designed to improve the energy absorption of the vehicle during a side impact by involving the front floor panel 11 in the energy absorption during the side impact. The front floor reinforcement structure 1 includes a front floor cross member 13 having a non-deformable portion 14 located on the end of the front floor cross member 13 closest to the side sill 9 and a deformable portion 16 located on the end of the front floor cross member 13 closest to the tunnel 7. The resistance to plastic deformation of the non-deformable portion 14 is greater than the resistance to plastic deformation of the deformable portion 16, which is itself greater than the resistance to plastic deformation of the front floor panel 11.

Abstract: A computerized method to determine the aptitude of a metallic part to be manufactured by roll forming and to classify metallic parts into one of the following categories: roll-formable without modification, roll-formable with modifications, not roll-formable. It also provides for a computerized method to compute the roll forming direction of a part. It further provides a method for determining the aptitude to roll forming of a large set of parts, such as for example part of the set of parts making up an automotive vehicle. The purpose of the current invention is further to provide a manufacturing method for a metallic part.
