Abstract The present paper investigates the vibration behavior of the thermally buckled shape memory alloy (SMA) fiber-reinforced composite plates. The stress-strain relations are developed for a thin composite lamina with embedded SMA fibers. The finite element equation of motion including shape memory effect is presented. This equation can be mathematically separated into a static equation and a dynamic equation. The thermal postbuckling deflection and vibration of the thermally buckled position for SMA fiber-reinforced composite plates are determined. Due to the effects of nonlinear material properties of SMA, the vibration characteristics of thermally buckled composite plate with embedded SMA fibers are distinctly different from the one without SMA. Thermal postbuckling, natural frequencies and vibration modes for SMA reinforced composite rectangular plates are presented. Triangular plates with simply supported and clamped boundary conditions are also studied.
