چکیده:

The axial vibrations in a thin layer of finite cylinder made of trigonal(3m)piezoelectric crystal are investigated. By using a closed form solution ofthe equations of motion and applying new boundary conditions the effects ofthe geometrical dimensions,axial hydrostatic pressure,and electrostaticpotential along the axis of the cylinder shell on oscillation frequency andamplitude of spatial vibrations are simulated
