【摘要】 以VC++为编程工具,编制了可视化程序,提出了混凝土任意形状骨料及其界面层的二维生成算法,在该算法的基础上,利用AutoCAD为二次开发工具生成了具有任意形状骨料及界面层的二维混凝土试件几何模型和有限元网格模型。该模型能很好地模拟人工骨料和再生骨料,从而为细观结构研究提供了有效的建模工具,为进一步的复合材料多尺度分析奠定了基础。更多还原

【Abstract】 A visual program was designed in VC++ to build geometrical model.At the same time,2-D generation algorithm for concrete aggregate of arbitrary shape and its bond layer was advised.On the base of geometrical model,a finite element mesh model was built using AutoCAD software and the algorithm.The artificial or regenerated aggregates model can be simulated by these models.An effective modeling tool for the research on microstructure and multi-scale analysis of the multiphase composite can be improved based on the method mentioned.更多还原
