This study introduces a novel Ritz approximation function to analyze the free vibrations of laminated composite shallow curved beams. The methodology utilizes polynomial functions-based Fibonacci series to develop the Ritz’s approximation function. The displacement field aligns with the high-order shear deformation theory designed explicitly for shallow curved beams.
