Abstract:The present paper describes some engineering oriented approaches employed in structural shape optimization. A geometry-based approach has been used to integrate modelings of three phases, i.e. structural shape modeling, design optimization modeling and finite element modeling. The strategy of user's programming interfaces is proposed to deal with special application problems and make optimization program really flexible. The versatile sensitivity analysis is implemented with semi-analytical scheme, which is particularly efficient to compute the design sensitivity with respect to variations of load, temperature and boundary conditions caused by shape changes. These approaches have been proved to be practically valuable by the development and application of a general purpose package of micro-computer aided optimum design for structures, MCADS. Two application examples of MCADS, dealing with optimum shape design of continuum structures coupling fields of stress and temperature, are presented.
