The boundary element method formulation is applied to a forced steady-state vibration problem of thin-walled plate structures. The integral equations for in-plane motion are derived using three types of fundamental solution : one for elastostatics, and the conventional one for elastodynamics and its expanded form. On the other hand, the static fundamental solution is employed for the derivation of the integral equations for out-of-plane motion. All the integral equations used in the analysis are regularized up to an integrable order and then discretized by means of the boundary-domain-element method. The entire system of equations for the plate structures composed of plate elements is obtained by assembling the equations for each plate element to satisfy the equilibrium and compatibility conditions on the assembled edge. Numerical analysis is carried out for a few examples, and the computational aspects of the different formulations of in-plane motion are discussed.
