单轴状态下混凝土的动力损伤本构模型

Dynamic damage constitutive model of concrete in uniaxial tension and compressiom

本文根据现有的混凝土静力损伤本构模型，结合混凝土在快速变形下的性能试验成果，提出一定的假定，推得混凝土的动力损伤本构方程．经与单拉和单压状态下的试验成果对比证实，本文提出的理论模型能够较好地描述真实变形过程．

Based on the static damage constitutive model,two hypothesises have been proposed by the authors and a dynamic damage constitutive model of concrete under uniaxial tension or compression has been deduced. This model was witnessed by the experimental result.
