Electroelastic field in a piezoelectric solid cylinder with D∞ symmetry subjected to transverse mechanical load

For the safe operation of devices comprised of bodies with D∞ symmetry, the electroelastic field in a solid cylinder subjected to a non-axisymmetric surface load of radial and circumferential stresses was investigated. The analytical technique constructed previously, the Fourier integral technique w...
