This article presents an analytical study for forced vibration of a cylindrical shell which is composed of a functionally graded piezoelectric material (FGPM). The cylindrical shell is assumed to have two-constituent material distributions through the thickness of the structure. and material properties of the cylindrical shell are assumed to vary according to a power-law distribution ... https://www.lightemupsequences.com/discount-HANCHENG-CHINA-hot-buy/
