Abstract

A refined higher order theory based finite element model is developed for modeling the dynamic response of delaminated smart composite plates. The theory assures an accurate description of displacement field and the satisfaction of stress-free boundary conditions at all free surfaces including delamination interfaces. A nonlinear induced strain model is used. Vibration control is obtained trough piezoelectric layers bonded on the composite plate. The theory is implemented using finite element technique which allows incorporation of practical geometries and boundary conditions, various sizes and locations of delaminations as well as discrete sensors and actuators. The resulting model is shown to agree well with published experimental data. Significant changes in dynamic properties are observed due to the presence of delamination.
