By introducing displacement functions as well as stress functions, two independent state equations with variable coe$cients are established from the three-dimensional equations of a radially inhomogeneous spherically isotropic piezoelastic medium. By virtue of the laminated approximation method, the

A three-dimensional analysis is carried out for the free vibrations of a multi-layered spherically isotropic hollow sphere using a state-space method. By the introduction of three displacement functions and two stress functions, two independent state equations with varying coe$cients are derived. Ta
## Abstract Metal hollow sphere structures represent a new material group. Within the design progress classical materials are replaced by these new class when a series of physical / mechanical requirements are touched. Typical requirements are related to strength, stiffness, electrical or thermal c
A uniformizing method is presented for the free vibration analysis of metal-piezoceramic composite thin plates which are popular structures of thin plate-type ultrasonic motors. A metal-piezoceramic composite thin plate is normally composed of a metal plate with one surface adhering to a piezoelectr
