摘要
主要针对爆炸冲击载荷作用下板壳结构的试验破坏问题,利用LS-DYNA有限元分析软件,采用非线性动力学分析计算方法,考虑材料非线性和结构非线性等因素,模拟分析了板壳结构在接触爆炸冲击载荷作用下的动态响应。计算分析结果与试验结果相吻合,利用有限元分析方法能很方便解释试验过程和现象,为试验分析提供有效依据。
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.
