摘要

摘要: 混凝土内部微细观结构影响其损伤和破坏行为.鉴于传统连续介质力学在模拟混凝土损伤累积和渐进破坏过程中存在的问题，基于数值图像技术获得混凝土试件的内部骨料形态，采用键型近场动力学理论，建立了能够考虑混凝土非均质特性的近场动力学模型，并在ABAQUS平台下开发了相应的计算模块，进行了混凝土试样的拉伸和压缩细观破坏分析.结果表明：近场动力学模型和数值方法能够成功模拟混凝土材料的复杂破坏过程，得到的破坏现象与试验结果吻合程度较好，进一步探究了混凝土材料的破坏机制，完善了混凝土结构的破坏分析过程.

Abstract: The classical continuum mechanics and some related numerical methods often fail in analysis of the damage evolution and progressive failure process of concrete materials, due to the difficulties in handling discontinuity and considering the intrinsic microstructure, which is of significance to the damage evolution. A peridynamic concrete model in view of the heterogeneity was established. The digital image processing (DIP) technology was firstly adopted to extract the information of aggregate shape and distribution in a concrete specimen, and then the bondbased peridynamic model reflecting 3 different bonds was applied to analyze the tension and compression failure of standard concrete specimens. The proposed analysis tool was further developed with the FORTRAN language in the framework of ABAQUS. The numerical results are in good agreement with reported experimental data, indicating that the proposed peridynamic model for heterogeneous concrete can simulate the complex failure process of concrete well, and paves a way to further exploration of the failure mechanism of concrete materials.
