Abstract Composite materials are being investigated in advanced technology test beds for use in future armored vehicles. We are particularly interested in the response to impulsive loading for which the knowledge of natural frequency behavior is important. In this paper, we investigate the natural frequency analysis capabilities of the multilayered shell element of the ADINA finite element code as applied to laminated composite beams and plates. Results are compared to those published in the literature or those derived from exact solutions. The ADINA shell element employs a first-order shear deformation theory, and the results are found to agree well with other first-order theories. Although ADINA does not allow for a direct method of incorporating a shear correction factor commonly used in first-order theories, it is demonstrated how this can be included by modifying the material properties.
