Available methods for discrete variable structural optimization are reviewed in this paper. Methods are classified according to three categories: branch and bound, approximations using branch and bound, and ad-hoc methods. The branch and bound method

An improved approximation for stresses (and strains) in plate structures is presented. This approximation is highly accurate because it is based on approximations of the element forces, which are more invariant than the element stresses and strains,

The proposed method is based on the concept of providing linearized information between the system level and subsystem level optimization tasks. The advantages of the method are that it does not require optimum sensitivities, nonlinear equality const
