摘    要:为评估ABAQUS有限元软件中混凝土损伤塑性模型分析混凝土材料和构件静力性能的能力,用该模型对混凝土材料单轴、双轴应力状态下力学性能以及构件的抗弯、抗剪性能进行模拟,并与试验结果进行对比分析.结果表明,混凝土损伤塑性模型可以较为精确地模拟单轴受压、单轴受拉、双轴受压以及双轴受拉状态下混凝土材料的力学性能,能较好地反映双轴应力状态下的材料破坏包络线,也能较好地预测钢筋混凝土构件的抗弯和抗剪性能及其破坏特征,但不能很好地描述双轴拉压应力状态下混凝土材料的力学性能,也不能反映材料的体积应变发展变化规律.

关 键 词:ABAQUS  混凝土损伤塑性模型  有限元  力学性能  抗弯性能  抗剪性能  ABAQUS  混凝土  损伤塑性模型  性能分析  concrete  model  plasticity  properties  static  变化规律  发展  体积应变  双轴拉压  描述  破坏特征  钢筋  预测  破坏包络线  应力状态  双轴受压

Abstract:To evaluate the capacity of the damaged plasticity model for concrete in the finite element software ABAQUS to analyze the mechanical properties of concrete material and structure, the model was adopted to simulate the mechanical properties of the concrete under uniaxial and biaxial stress conditions, the flexural properties and shear strength of concrete structures. The numerical results were compared with the test data. The results show that the model could simulate the mechanical properties of concrete material under uniaxial compression, uniaxial tension, biaxial compression and biaxial tension conditions, and that the model could reflect the failure envelope of concrete material under biaxial stress condition properly. The model could predict the flexural and shear properties, as well as the typical failure modes of concrete structures. However, the model could not predict the mechanical properties of concrete material under biaxial tension and compression condition, and the development law of the volumetric strain of the concrete.
Keywords:ABAQUS  damaged plasticity model for concrete  finite element  mechanical property  flexural property  shear property
