Dynamic Analysis of Laminated Composite Plate Integrated with a Piezoelectric Actuator Using Four-Variable Refined Plate Theory

摘要: This paper presents an analytical solution based on four-variable refined plate theory for dynamic analysis of cross-ply composite laminates integrated with piezoelectric fiber-reinforced actuator attached to the upper surface. considers parabolic transverse shear strains through thickness. Equations motion simply supported rectangular plates are derived using Hamilton’s principle, and Navier’s method is employed solve equations. An unconditionally stable implicit Newmark scheme used temporal discretization. The accuracy present proved by comparing results those obtained finite element analysis. effects different parameters such as thickness-to-side ratio, aspect ratios types mechanical electrical loading deflections stresses investigated.
