基于细观混凝土模型的刚性弹体正侵彻弹道偏转分析
On ballistic trajectory of rigid projectile normal penetration based on a meso-scopic concrete model
摘要
Abstract
To study the effect of the concrete's mesoscopic factors on the deflection of the rigid projectile's ballistic trajectory,we established a 3-D mesoscopic model for the concrete based on the idea of randomly distributed aggregates,analyzed the causes and possible contributing factors of the ballistic trajectory deflection of the rigid projectile penetrating into a concrete target,and examined quantitatively the influence of the mesoscopic factors of the concrete.The results show that the mesoscopic concrete model is able to reflect the typical physical phenomena of a projectile's normal penetration,that the mesoscopic factors have significant effect on the deflection of the ballistic trajectory as the rigid projectile is penetrating into the mesoscopic concrete,and that there exists a characteristic ratio of the projectile's diameter to the largest possible diameter of the aggregate.关键词
