Axisymmetric vibration of piezocomposite hollow circular cylinder. (English)
[J] Acta Mech. 116, No.1-4, 213-222 (1996). ISSN 0001-5970; ISSN 1619-6937/e

Summary: The axisymmetric vibration of a piezoelectric laminated hollow circular cylinder has been studied for an imperfect interface model. The frequency equation is derived for traction free inner and outer surfaces of the hollow cylinder with continuity conditions at the bonding interfaces. The composite cylinder is composed of two different piezoelectric materials belonging to 6 mm class and a hypothetical linear elastic material with voids (LEMV) as bonding layer. Numerical solutions of the frequency equation are obtained for the composite cylinder ceramic(1)/LEMV/ceramic(2). Computational results are presented as dispersion curves as well as in tables to characterize the attenuation of axial waves for three layered cylinders with and without voids in the thin LEMV layer.
