【Abstract】 The shape of an elastic body suffered plane stress is optimized by boundary element method and sequential uncostrained minimization techni-que.In process of optimization, the multiple objective problem is treated by fictitous objective method.To avoid tedious sensitivity analysis the "new simplex method" is used and the satisfactory result of the example is obtained.更多还原
