| Abstract: | The principle and the expected result of reducing forming load of the twist-compression forming process are analysed by the theory of plasticity.The strain distribution of the process is predicted by SEM analysis.Both upsetting and processes are simulated by using plasticine as model material,the evolution process of the cavities in the cylinder is observed.The experimental results are coincided with the analysis ones. |
