The goal of this study is to investigate the effect of the initial stress and transverse isotropy on the dispersion relation of flexural wave in a conducting circular cylinder subject to the initial state of stress of the form of hydrostatic tension or compression. The free stress conditions on the inner and outer surfaces of the hollow circular cylinder were used to form the dispersion relatio...

This paper is devoted to study a problem of plane waves reflection at a traction-free surface of a pre-stressed functionally graded piezoelectric material (FGPM). The effects of initial stress and material gradient on the reflection of plane waves are studied in this paper. Secular equation has been derived analytically for the pre-stressed FGPM half-space and used to show the existence of two ...
