| Abstract: | Aiming at the experimental damage problem of shell structure subjected to explosion impact load,the dynamic response of shell structure subjected to contact explosion impact load is simulated with the use of the finite element analysis software LS-DYNA,and using the nonlinearity dynamic analysis method,considering the material nonlinearity and structural nonlinearity.The analysis results and experimental results coincide with,the finite element method is very easy to explain the experimental process and experimental phenomenon,provide the effective basis for experimental analysis. |
