摘要
为了清楚认识横向受压薄壁圆钢管在冲击波作用下的变形特征,本文在已有实验的基础上,运用有限元软件LS—DYNA对横向受压薄壁圆钢管在爆炸冲击波作用下的压扁过程进行了数值模拟,利用LS—DYNA后处理功能分析了在爆炸冲击波作用下钢管动态变形过程。
To understand the deformation characteristic of transverse pressured thin-wall circular steel tube under shock wave, this article used finite element software LS-DYNA to simulate its flattening behavior under explosive shock wave, then analyzed the dynamical deformation process of steel tube through the post-processing function of this software.
