A method of the structural synthesis in terms of the boundary element method is presented. The synthesis aims at the shape modification required to decrease the stress concentration in the elastic plane stress state. The method is based on the sensitivities of the boundary element solution and the notion that the objective design is searched as near the baseline design as possible. The effect of indeterminate loading and objective stress is taken into account so that the objective design is obtained with the latitude of shapes. The indeterminacy of the resultant shapes is evaluated in the form of the nodal coordinates taken as the design variables. The numerical examples concerning the flat plates with opening under tensile loading verify the validity of the formulation presented in order to decrease the surface stress near the fillet corner.
