The frustum is shell-walled, having a central recess opening to the rear and extending forwardly into the head portion. The head portion has a parabolically shaped outer surface which transitions smoothly into a hyperbolically shaped outer skirt surface for aerodynamic efficiency. Vanes are formed on the head portion to enhance in-flight spiraling rotation.

The rear-floor cross member braces are connected to the body part (51) of the second rear-floor cross member. Shock energy of a shock load applied to the vehicle body rear part from the rear can be absorbed efficiently while the deformation of a rectangular region surrounded by the first and second rear-floor cross members and the right and left rear-floor cross member braces is restrained.

An electro-hydraulic forming tool is disclosed in which a membrane is retained between two volumes of liquid that are separated by a membrane. Electrodes are provided with a high voltage impulse to create a shockwave in one of the volumes of fluid that is transferred through the membrane to the other volume of fluid. The shockwave is transmitted to a blank that is formed into a one-sided die. The blank is formed against the forming surface of the die. Air evacuation means are provided to remove air from the upper surface of one or both volumes of liquid.

A casing for a steam or gas turbine comprises a shell and two flanges. The wall thickness of the shell is varied in an upper region facing away from the flange, in two central regions and in two lower regions facing the flanges, such that the upper region facing away from the flanges is reinforced in comparison with the lower regions facing the flanges. The lower regions facing the flanges are more flexible than the flanges which are attached by screws, and the partially reinforced central region and the reinforced upper region, and act as a joint to compensate for deformation, particularly in the radial direction. Consequently, the casing remains considerably more round in operation. The reduced radial clearance (achieved by reduced deformation) between the casing and the ends of the turbine blades leads to considerably increased efficiency during operation of the turbine.
