Description
Summary:A finite element formulation is developed to model the response of laminated composite plates containing distributed piezoceramic actuators and senors. The stress equations of motion are derived usng the variational principle with respect to the total structural and electrical potential energy. These stress equations are converted to a two-dimensional finite element equation is based on the QUAD4 isoparametric quadrilateral element which is currently used in such FEA codes as COSMIC/NASTRAN and ASTROS. This new piezoelectric finite element formulation was incorporated into an FEA computer code and validated by comparison with published experimental and numerical results.
