Finite Element Analysis of Fragment Penetrating Target by LS-DYNA
Author(s): 
Pages: 4-5,11
Year: Issue:  2
Journal: ORDNANCE INDUSTRY AUTOMATION

Keyword:  有限元分析LS-DYNA破片侵彻;
Abstract: 基于LS-DYNA的破片侵彻靶板有限元分析分为前处理、求解和后处理.前处理设置单元属性,构建模型,划分网格、定义接触、初始条件、载荷及约束、求解时间和输出文件等.用LS-DYNA修改前处理输出文件,进行递交运算.再用LS-PREPOST刷新速度、查看结果,动画模拟过程,得出能量、速度、冲击力、应力等变化曲线.并以球形破片侵彻靶板为例进行了分析和验证.
