Nonstationary Axisymmetric Problem Of Electroelasticity For A Piezoceramic Cylinder With Circular Polarization

摘要

This paper considers the problem of the propagation of forced electroelastic axisymmetric torsional waves in a hollow piezoceramic cylinder of finite dimensions, whose curvilinear electroded surfaces are subjected to shear stresses or an electrical potential. A new closed solution is constructed by expansion in vector eigenfunctions using the structural algorithm of finite integral transforms, which makes it possible to determine vibration eigen)frequencies, the stress-strain state of the element, and the potential and intensity of the induced electrical field.
