Abstract：

The rigid visco plastic finite element model of shell nosing has been established in this paper,the stress and strain distribution and the defect which appears in shell has been analyzed at different friction factor.To obtain the expected configuration and dimension of shell blank,the friction factor at die blank interface is less than 0 15
