This paper is concerned with the boundary element method for the elastic buckling analysis of assembled plate structures. First, we discuss a boundary element approach to the elastic buckling problem of a single plate with arbitrary from subjected to any boundary conditions. The so called boundary-volume element method is used for the numerical solution of the resulting integral equations. Thus, the final set of equations can be reduced to algebraic eigenvalue equations. Next, the proposed method of solution is extended to the elastic buckling analysis of assembled plate structures. Numerical implementation of the compatibility and equilibrium equations on the joined edge is discussed in some detail. Finally, a few sample problems are computed and the results obtained are compared with other solutions, whereby the usefulness of the proposed method is demonstrated.
