SHAPE OPTIMIZATION BY BIOLOGICAL GROWTH STRAIN METHOD-MINIMIZATION OF STRESS CONCENTRATION

With the advent of structural optimization, the researches for shape optimization have also been under development with growing interest. In this research, in order to minimize the stress concentration, one optimal shape design method originated from the concept of biological adaptation process was proposed. The characteristic of this new method is in no need of structural sensitivity analysis. The algorithm and availability of this method was explained and verified in this paper. In addition, the excellence of computation efficiency of this method was also illustrated.
