An Investigation on the Nose Mass Abrasion of Projectile

摘要

Based on the dynamic spherical cavity expansion theory of concrete and the analysis of experimental data, a mass abrasion model of projectile considering the hardness of aggregates, the relative strength of target and projectile and the initial impact velocity is constructed in this paper. The results indicate: the initial impact velocity is the most important factor of mass abrasion. The hardness of aggregates and the strength of projectile are also the significant factors of mass abrasion. However, relatively speaking, the sensitivity of strength of projectile to mass abrasion is higher, which indicates that the effect of projectile material on mass abrasion is more important than the hardness of aggregates.
