N2 - A refined modeling technique is developed to analyze the effect of delamination on a composite plate with piezoelectric actuators. The analysis uses a refined displacement field, which carefully accounts for both the presence of delamination and distributed actuators. The effect of delamination is investigated under both static and dynamic conditions. The analysis is implemented using the finite element method. Numerical results presented indicate the significant changes in mechanical parameters due to a small delamination. These results can be useful for on line damage detection.
