The effect of delamination on composite beam specimens with active piezoelectric sensors is analysed using a piecewise linear layerwise laminate theory. The model naturally includes, among other things, the excitation of piezoactuators, a coupled electromechanical system and the effect of the actuation on the piezoceramic sensors. The developed model has the ability to describe linearly through the thickness of each layer the displacement and the electrical field. Also the model describes the effect of various delamination cracks at the displacements field as additional degrees of freedom and naturally includes the effect of interfacial contact. The quasistatic and the transient response of the delaminated composite beams are predicted and the damage effects are investigated. Also the effect of interface contact on the response of delaminated beams with active piezoelectric sensors is further quantified.
