Abstract
A plate structure includes a plate having a planar portion defining a datum plane. The plate includes a raised bead seal and a tunnel protruding away from the datum plane. The raised bead seal extends along a centerline laying on the datum plane. The tunnel extends along a path laying on the datum plane. The tunnel intersects the raised bead seal. The path and the centerline intersect to form a first intersection angle and an adjacent second intersection angle on the datum plane. The first intersection angle and the second intersection angle are supplementary angles. The first intersection angle is an acute angle, and the second intersection angle is an obtuse angle. The path and the centerline are arranged to form a specific value of the first intersection angle and the second intersection angle to control a stiffness of the raised bead seal.
