摘要/Abstract

摘要： 本文对I-LJC状态方程作了进一步改进，同时给出了一种混凝土的拉伸损伤计算模型，然后采用改进的LT2-2D程序模拟了混凝土靶板的损伤破坏情况。计算结果一方面验证了混凝土的抗压能力对弹体的侵彻过程起主要作用，而抗拉能力最终影响其损伤破坏情况；另一方面也说明了在分析弹体的侵彻过程和混凝土靶板损伤破坏上，本文给出的计算模型具有一定的适用性。此外，本文还分析了混凝土材料的细观特性对其损伤破坏的影响。

Abstract: The computational constitutive model of HJC for concrete was improved further, and a ten?sile damage model of the concrete target plate was presented. Damage of the plate was simulated by above models based on the improved LTZ-2D code. The computed results show that penetration pro?cess is dominated by the plate compressive strength, final damaged state of the plate is significantly in?fluenced by tensile strength and mesomechanical characteristic has influence on damage of the plate. The proposed models are suitable for analyzing penetrating process of the projectile and damage of the plate.
