Dynamic optimal design of structural systems with local non‐linearities is proposed and the corresponding mathematical programming is established in this paper. A predictor‐corrector method is presented for state and sensitivity analysis of the systems which is based on partitioning and interface prediction of linear and non‐linear regions. The non‐linear programming problem is linearized and solved by a coarse search SLP approach. A model of an automatic weapon is optimized and some interesting results are given to illustrate the effectiveness of the present method.
