For example, in Fig. thecase for m = 1, n = 1, p = 2 is shown which simply means that the highfrequency shear on the front half of the plate is out of phase with that of the 58 BELL SYSTEM TECHNICAL JOURNAL back half of the plate. This discussion relates only to the case of the highfrequency shear commonly assumed to be a single shear along the length andthickness of the plate. Similar statements can be made if we considerthe high frequency shear as being along the width and thickness.
