在Ls-Dyna下整个仿真评估流程如下
一、模型构建
二、材料定义
三、单元算法定义
四、状态方程控制
五、属性赋予
六、连接关系设置
七、边界与载荷条件
八、求解设置
九、求解
十、结果解读
采用hypermesh进行建模，最终效果如图1所示
图1
采用20号刚体材料*MAT_RIGID以及24号材料*MAT_PIECEWISE_LINEAR_PLASTICITY进行定义，具体设置如图2所示。
图2
采用关键字*SECTION_SHELL针对壳体进行单元算法和厚度定义定义，更改厚度为1.54，采用*SECTION_SOLID进行实体算法定义，具体设置如图3所示；
图3
无状态方程定义
将定义好的材料以及单元算法赋予给对应part，如图4所示；
图4
通过设置*ONTACT_ERODING_SINGLE_SURFACE，注意相关关键字的选值，具体设置如图5所示。
图5
本模型仿真采用*BOUNDARY_SPC_NODE约束立柱下表面，同时采用*INITIAL_VELOCITY_GENERATION施加初速度，具体如图6所示。
图6
采用*CONTROL_TERMINATION 进行整个截止时间的定义，
*DATABASE_BINARY_D3PLOT定义结果输出间隔，
*CONTROL_ENERGY控制能量输出
具体设置如图7所示
图7
将k文件输入dyna进行求解，需要控制求解线程数和求解内存，如图8所示
图8
最终结果如图9所示
