The parabolic KS function for the structural topology optimization

摘要

This paper is devoted to the parabolic KS function for the structural topology optimization and presents a different strategy to deal with the minimum stress design problem. We transform the local stresses to global integrated stress of structure through the parabolic KS function. A new optimization model is introduced which provide quality solutions and the minimum stress design to obtain the final design. Finally, the parabolic KS function is important because we firstly introduce a different KS function to study the structural topology optimization problem.
