Natural frequencies of a multilayer composite plate with shape memory alloy wires
The results presented in this study are obtained for a shape memory alloy (SMA) fibre-reinforced multilayer composite plate made of graphite-epoxy composite. The influence of SMA fibres upon natural frequencies of the plate is investigated. The constitutive relations for a composite plate with embedded SMA fibres are developed. Finite element governing equations and solution procedures for the SMA fibre-reinforced composite plate are also presented. The results of numerical calculations show that the SMA fibres can greatly influence in the natural frequencies of the plate.
