One embodiment includes providing a contiguous tubular member including at least one of a first material or a second material, so that the tubular member has a wall thickness that varies along the length of the tubular member; bending the tubular member; and hydroforming the tubular member into a part.

Multi-thickness tube for hydroformed members

A method includes acquiring a first structural component conforming to a design, producing a first vehicle including the first structural component, and transferring possession of the first vehicle with the first structural component having a first set of mechanical properties. The method further includes acquiring a second structural component conforming to the design, subjecting the second structural component to a heat treatment process so that the second structural component is characterized by a second set of mechanical properties different from the first set of mechanical properties, producing a second vehicle including the second structural component, and transferring possession of the second vehicle with the second structural component having the second set of mechanical properties.

Method of varying material properties

Reconfigurable bins include at least one structural component formed of shape memory materials such as a shape memory polymer, a shape memory alloy, or a combination thereof. The shape memory material is in operative communication with an activation device adapted to provide an activation signal effective to change at least one attribute of the shape memory material such that the bin can be reconfigured from a first shape to a second shape. The reconfigurable bin can include a mesh network or may be formed of panels or a combination panels and mesh.

An underbody for a vehicle includes a floorpan defining a part of an assembly, a rocker slidably engaged with the floorpan, and a rail slidably engaged with the floorpan. The assembly is formed as a unit about a first and a second bend axis.

Vehicle underbody and method of forming thereof

An equipment (engine) compartment at one end of an automotive vehicle is closed by a structurally stiff hood panel having laterally opposite edges supported in side rails. The hood panel is longitudinally slidable in the side rails between a closed position covering an upper opening and an open position wherein the hood panel is moved to a longitudinally outward position along the rails to open the compartment for servicing equipment in the compartment. Releasable latches hold the hood panel closed until released for sliding to the open position with a releasable stop for full removal of the panel. The hood panel and side rails are preferably extruded members forming structurally stiff box sections that provide significant energy absorption to the front structure of the vehicle.
