Shape memory alloy (SMA) wires are embedded within laminated composite plates to take advantage of the shape memory effect property of the SMA. Active modal modifications of laminated composite plates with SMA wires are studied using finite element method. A linear finite element model and its source codes were developed for this purpose. The plate-bending model used in this study was developed based on the first order shear deformation theory (FSDT) and the finite element model used is the serendipity quadrilateral element with 40 degree of freedoms per element. The effect of SMA is captured by adding the geometric stiffness matrix to the typical stiffness matrix of composite plates. With the mass matrix, the typical eigen-value problem is solved where the eigen values represent the natural frequencies of the plates. Two methods of frequency improvement are considered here: The active property tuning (APT) and the active strain energy tuning (ASET). The values of recovery stresses for the ASET improvement of the SMA are determined from the Brinson’s model. Studies are conducted on the anti-symmetric angle ply SMA laminated composite plates. The effect of several parameters such as geometric, mechanical and transformation effects on the natural frequencies and the mode shapes of the SMA composite plates are studied. It was found that the effect of SMA is similar for couples of frequency modes where frequencies of mode I and IV seems to have the greatest effect in the case of simply supported and clamped-clamped boundary conditions.
