Structural Optimization has progressed significantly in the past twenty years and is now commonly used in the design of mechanical and aeronautical components. A multitude of optimization programs exist and may have been incorporated in finite element programs and are an integral part of that design tool. Problems consisting of single discipline like structural, vibrational etc., have been dealt with successfully by researchers. However very little has gone into multidisciplinary problems such as the design of an Aircraft, which involves structural, aerodynamic, control and other disciplines. In these cases, sequentially generated optimized solutions of individual disciplines need not necessarily lead to a global optimum solution for a coupled problem. The interdisciplinary effects play a major role in reaching a globally optimized design.
This work is aimed at testing the use of the Two point exponential approximation for formulating an efficient procedure for coupling multiple disciplines sensing the effect of one discipline over another.
