The natural frequencies and mode shapes of thin and moderately thick rhombic plates are obtained using a 9‐noded Lagrangian quadrilateral isoparametric plate element based on Mindlin's theory. The effects of rotatory inertia are included. Plates with a wide range of skew angles and boundary conditions are considered and wherever possible the present results are compared with earlier published work.
