The Steady-state response is presented for a damped cantilever annular sector plate with curved radial edges and varying thickness by the Ritz method. The plate is transformed into a regular sector plate with unit outer radius by a transformation of variables. The transverse displacement of the transformed plate is approximately expressed in series of the power function. Substituting the expression for the kinetic energy and strain energy of the plate into a Lagrange equation, we analytically derive the dynamic response of the plate. The numerical examples are calculated for two types of annular sector plates with symmetrically and unsymmetrically curved radial edges. The effects of the damping factor and varying thickness are clarified quantitatively on the steady-state responses of the plate.
