【摘要】 系统综述了基于细观损伤的混凝土力学性能数值模拟的研究现状,介绍了细观损伤力学在混凝土性能分析中的应用。重点对微平面模型、二维格构模型、随机粒子模型、细观结构模型、可考虑微裂纹间相互作用的细观损伤模型、基于弹性损伤本构关系的细观结构模型及Gurson细观损伤模型等几种常用的基于细观损伤的混凝土本构模型的优、缺点进行了比较。最后指出了以后有待进一步研究的问题。更多还原

【Abstract】 In this paper, the researches of mechanical performance of concrete based on micro-mechanics damage are completely reviewed and the application of micromechanics in the research of concrete performance is presented. The merits and defects of some kinds of constitutive model of concrete based on micro-mechanics damage, such as micro-plane model, lattice model, random particle model, micromechanical model, micro-mechanics damage model considering the effect of micro-crack, micromechanical model based on elastic constitutive relation, micro-mechanics damage model based on porous media, are compared in detail. Furthermore, the further problems in this field are discussed.更多还原
