8.18 Transverse Vibration of Rectangular Thin Plates
A body having its middle surface (the surface obtained by bisecting the upper and
the lower face of the plate) in the form of a plane and whose thickness is sufficiently
small compared to its other two dimensions is called a thin plate. In deriving the
theory, the following assumptions are made:
(1) A normal to the middle surface of the plate before bending, trans-forms into a
normal to the middle surface after bending.
