摘要

摘要: 混凝土是一种应用广泛的复合材料，其动态性能及抗侵彻毁伤效应的研究越来越依赖于数值模拟，其中混凝土HJC模型是应用最广泛的本构模型之一。在介绍HJC模型的基础上，应用LS-DYNA数值模拟方法进行HJC本构模型抗侵彻性能的参数敏感性研究，通过大量数值模拟得出HJC模型的抗侵彻敏感参数有：无侧限单轴抗压强度fc、压实点压力plock、特征化粘性强度A、特征化压力硬化因子B和压力硬化指数N。在混凝土的抗侵彻数值模拟过程中，重点是确定敏感参数的取值，以提高数值模拟的精度和质量，做到合理地选择试验方法和安排试验量。

Abstract: Concrete is a widely used composite. The study of dynamic performance and anti-penetration effects on concrete is dependent on the numerical simulation, and the HJC model is often used in numerical simulations. On the basis of introduction about HJC model, parameter sensitivity analysis on HJC model by LS-DYNA numerical simulations is studied in the paper. There are five parameters (fc, plock, A, B and N) are sensitive. According to the sensitivity parameters, it can improve the accuracy and quality of numerical simulation and the reasonable test methods and arrangements for testing chosen.
