Abstract: The study of equilibrium configurations in structural mechanics leads to the necessity of obtaining numerical solutions of high order elliptic boundary-value problems. A method is presented for the solution of these problems in realistic geometries. The method is based on considering a given irregular region as imbedded in a simple region such as a rectangle and working with the variational problem corresponding to the given partial differential equation. The original boundary conditions become linear constraints. A discretized version of the resulting problem is then solved using dynamic programming. Existence and stability are demonstrated in the case of the potential equation.
