Two-dimensional equations of motion of doubly-rotated quartz plates for the thickness-shear, flexure, and extensional vibrations under in-plane initial stresses are employed to predict changes in the fundamental thickness-shear frequencies due to initial stresses. Two types of initial stresses are considered stresses due to a pair of diametral forces, and 2 stresses due to steady accelerations for a three-point T shaped mount and a four-point shaped mounted configurations. Force sensitivity and acceleration sensitivity coefficients are computed and compared with experimental data and existing computed results. For both T shaped and shaped mount configurations, mount orientations corresponding to the maximum and minimum of acceleration sensitivity are predicted. Author
