Different failure modes during the high-velocity penetration on the ship plate structure through material point method

  • 摘要: 本文通过数值模拟的方法研究了截卵型弹体冲击下921A钢板的毁伤模式。 跟以往试验进行对比,发现数值结果与实验结果吻合良好。 在3种不同工况下,剩余速度与实验结果吻合良好,误差小于5%。随着弹着点位置的变化,加筋板的失效模式发生变化。击中靶板中心时,加强筋发生撕裂,目标板在左右两侧产生对称的花瓣型破坏模式。 随着弹着点位置的偏移,加强筋的撕裂程度逐渐减小,最后仅仅发生塑性应变。并且目标板上的破坏不再对称,左侧板的动态响应从花瓣破坏变为小面积断裂,最后仅保留塑性变形。右侧板始终产生花瓣型失效模式,但花瓣的数量和形式始终在变化。结果表明,物质点法可以很好地应用,并为今后舰船穿透研究提供参考。
