[Abstract]: This paper presents a computer automated performance-based optimal design technique for topology design of continuum structures under multiple load cases. In the present method, the performance objective is to minimize the weight of a continuum structure subjected to system performance constraints. A two-level control scheme is implemented in optimization algorithms to achieve the optimum based on performance-based design criteria. The energy-based performance index is used to monitor the performance level of optimized topologies in an optimization process. Performance-based optimality criteria are used to identify the optimum from the optimization process. Examples are provided to demonstrate the capacity of the computer automated performance-based optimal design technique for continuum structures under multiple loading conditions. Results indicate that the PBO technique can results in weight savings of up to 44 percent compared to initial designs.
