Transient analysis of laminated composite plates with embedded smart-material layers

摘要

The transient response of laminated composite plates with embedded smart material layers is studied using a unified plate theory that includes the classical, first-order, and third-order plate theories. The simple velocity feedback control is used. The finite element method is used for numerical simulations, and numerical results are presented to study the effects of the lamination scheme, boundary conditions, and loading. As a specific example, Terfenol D magnetostrictive material layers are used to control the vibration suppression. The effect of material properties, smart layer position, and smart layer thickness on the vibration suppression is also investigated.
