| Abstract: | On the basis of elastoplastic theory and transient nonlinear finite element method,the explicit transient nonlinear finite element code DYTRAN and other CAD/CAE softwares are jointly employed to carry out a transient elastoplastic finite element modeling and analysis of an anti aircraft gun's receiver,which is subjected to contact and a strongly impulsive load.The space distributions and time responses of the effective stress and plastic strain in the receiver's stress concentration zone are evaluated.The results reveal the cause of cracking failure of the receiver in firing test. |

| Keywords: | nonlinear finite element impact load transient stress stress concentration gun components |
