The analysis of the propagation model of standing waves in an elastic plate with finite dimensions. The obtained results revealed that for the excitation of all modes of vibration of the plate is necessary to consider the phase shift at the points of its attachment, and excitation of asymmetric forms of natural oscillations with in-phase vibration exposure at the point of attachment is not possible. These data allowed us to develop a methodology of excitation of resonances in all forms of their own by introducing vibrational effect of the phase difference in the longitudinal, transverse and diagonal direction of the object of research.
