ABSTRACT:
A stress distribution plate, such as a diaphragm for a pressure transducer, has a central plane and a neutral stress plane. According to the invention, the neutral stress plane is displaced from the central plane, providing for a mechanical advantage or amplification in the operation of the stress plate or transducer. The stress plate or diaphragm may be provided with a lacunose surface region or with a predetermined and preferably symmetrical pattern of mesas and recesses for a displacement of the neutral stress plane relative to the central plane.
