-
The details as followed : 1. summarize and analyze the methods of meso - mechanics of concrete and researching documents on the theory of damage of concrete ; 2. based on the packing approach of spherical aggregates, a method generating polygon aggregate model of concrete was presented, by which the codes of aggregate packing and meso - meshes of finite element plotting were designed taking into account the actual aggregate content, grading, and aggregate configuration
具體工作由以下幾個方面: 1 .分析總結了混凝土細觀力學分析方法和現有混凝土材料損傷破壞理論的研究成果; 2 .在研究圓形骨料投放方法的基礎上，提出了一種多邊形隨機骨料投放方法，並編制了凸多邊形模型生成程序和細觀有限元剖分程序。這種生成方法所得到的凸多邊形骨料模型既反映了骨料的實際形態又維持骨料的實際級配和含量。
