| Abstract: | Several numerical problems in the numerical methodof shape optimum design for elastic continuum are discussed inthis paper, which are substructural algorithm of shape optimiza-tion, analytical calculation of sensitivity analysis, presentation ofmore accurate algorithm of step size for optimum design in whichthe weight is taken as the aim function. Based on these algori--thms, a program is designed to optimize the boundary shape ofthe planar continuum structures to minimize the weight. An exa-mple is given. |
