Steady state response to a sinusoidally varying transverse deflection is determined for an internally damped cantilever quadrilateral plate by means of the Ritz method. A quadrilateral plate of general shape is transformed into a square plate with unit length by a transformation of variables. The transverse displacement of the transformed square plate is approximately expressed in a series of the beam eigenfunction. Substituting the expressions for the kinetic energy and strain energy of the plate into Lagrange's equation, the equation of motion is developed. The dynamic response of the plate is determined by solving the equation of motion of the plate. Numerical work is done for the skew cantilever plate driven by a sinusoidally varying transverse deflection, and the steady state response of the plate is studied.
