| Abstract: | In this paper, the problems of stress-strain, strength and crack ofthe autofrettaged gun barrel are studied. Elasticoplastic stress-strain analysis ismade with the mixed hardening model, and the analytic expression are obtainedwhich are examined by experiments. The simalative formula of temperature fieldof the residual stresses is obtained. The stress intensity fiactors of the autofre-ttaged gun barrel with cracks are calculated by the finite element method. |
