Nonlinear dynamic analysis of laminated plates/shells with piezoelectric sensors and actuators

摘要

A finite element formulation using first-order shear deformation theory is used for vibration control of plates with piezoelectric sensors/actuators. The geometric nonlinearity based on von Karman's assumptions and structural damping in the form of Rayleigh damping are introduced in the present work. The formulation presented here, in general, is applicable for laminated composite structure. The dynamic responses are obtained using Newmark method coupled with iteration technique. The results pertaining to plates are presented.
