The sensitivity function characteristics used in optimal design by successive approximation are presented to obtain the minimal weight shape of a two dimensional structure with the constraint of elemental maximum equivalent stress. The sensitivity based on the summation of strain energy in the structure is presented to minimize the maximum equivalent stress or the weight of the structure. The values of the components of the sensitivity for the strain energy are easily obtained using the method to precalculate the surface displacements. The values of the components of the energy coincided well with those of the equivalent stresses in the examples of the initial shape and the shape in the midst of the optimization. The optimal shapes of two dimensional structures are acquired using the sensitivities, which can be developed to plate beam and truss structures.
