Abstract

An efficient method is presented for optimum design of plate and shell structures, when the design variables are continuous or discrete. The design variables can be sizing or shape variables. The efficiency of the method is based on the idea of force approximation in each design cycle. First a continuous variable optimization is achieved, by employing some approximate relations for element forces. Then a branch and bound method is used to obtain the discrete variable solution, using the same approximation concepts. A number of examples are offered to demonstrate the efficiency of the proposed method.
