| Abstract: | Materials selection optimization inherently belongs to discrete optimization design which is difficult to solve by traditional optimization algorithms.In this paper,materials selection optimization formulations for hybrid steel-composite with 0-1 topological design variables are presented.The solutions are obtained by the method of continuation with variables and mapping function transformation in optimization formulations.Taken dynamic optimization design of hybrid floating raft as an example,the optimizat... |
