ELECTROELASTIC TWO-DIMENSIONAL NONSTATIONARY VIBRATIONS OF A PIEZOCERAMIC PRISMATIC BODY UNDER MECHANICAL LOADING

摘要

We developed a numerical method for solving the plane problem of nonstationary vibrations of a piezoceramic prismatic body with rectangular cross-section under mechanical loading. How the vibrations of the body with clamped edge are excited and propagate is studied. The dynamic state of bodies of different widths is analyzed. The time dependence of the thickness and transverse displacements is plotted. The distribution of the electric potential over the width of the body is illustrated.
