This paper represents a new approach of the optimum design by the minimum strain energy criterion under the constant stracture weight. The criterion makes the structure design simpler than the minimum weight method, because there are fewer constraints considered at most. It is deduced, a series of nonlinear design equations for the criterion by Lagrange multiplier method, when it is assumed there is a homogeneous polynomial expression among design variables. The equations are solved numerically by an iteration method about the shell thickness distribution of axisymmetrical shell structures under transverse loads. The results showed remarkably both the decrease of stress concentrations and the increase of rididity of structure. It is indicated that the strain energy method is very powerful for optimum structure design as a whole.
