利用三维非线性有限元软件LS-DYNA对球形破片在不同速度以及不同入射角度下侵彻金属薄板的过程进行模拟,得出破片的极限穿透速度、剩余速度、剩余质量以及靶板的破坏模式等结果信息,总结出侵彻性能与破片初速度以及入射斜角的关系,以期能够为工程设计以及军事应用提供依据。
The three-dimensional non-linear finite element software LS-DYNA was used to simulate the penetration process of the spherical fragments at different speeds and angles of incidence. The ultimate penetration velocity, residual velocity, residual mass and damage modes And other results of the information, summed up the penetration velocity and the initial velocity of the fragment and the incidence angle, in order to provide a basis for engineering design and military applications.
