Abstract
A refined model for smart composite plates with delamination is developed. The modeling is based on a third order refined displacement field, which satisfies the stress free boundary conditions at all free surfaces including delamination interfaces. The displacement field also accounts for the presence of distributed piezoelectric actuators. The mathematical model is implemented using the finite element method. The dynamic strain is analyzed for smart composites with and without delamination. Next, a new approach is investigated for the detection of delamination in smart composites based on the Root-Mean Square (RMS) values of the plate response subject to disturbances. Numerical results presented show accurate location of the delamination and its size.
