| Abstract: | Using a commercial FE software ABAQUS,the forming process including springback of a U-channel was simulated by static implicit and dynamic explicit FEM respectively.The influence of blank holder force,friction condition and sheet thickness on springback was investigated.To minimize springback,the process parameters were optimized by Non-dominated Sorting Genetic Algorithm(NSGA-II) on Pareto combining with FEM simulation. |
