THICKNESS-TWIST VIBRATIONS OF AN INFINITE, MONOCLINIC, CRYSTAL PLATE.
Abstract
Thickness-twist modes of vibration of an infinite plate are standing waves with displacement and wave-normal at right angles to each other and parallel to the faces of the plate. In a monoclinic crystal plate, such waves are possible if the displacement is in the direction of the diagonal axis. The pertinent solution of the three-dimensional equations of elasticity for a plate with free faces is given, as well as another solution with the effect of the inertia of electrode films taken into account. The results are applicable to the rotated-Y-cut quartz plates used as oscillator and filter crystals in electric circuits. (Author)
