基于Python算法的混凝土球形骨料三维细观数值模拟方法

3D Meso-scale numerical simulation of concrete with spherical aggregates based on Python

介绍了一种混凝土构件三维细观数值模型及球形骨料参数随机投放算法。基于Python语言自身的优势以及与有限元软件的良好对接,使用Python语言编写程序实现了骨料生成、骨料几何参数有效性判断、混凝土构件几何模型建立及网格划分的过程,并借助钢筋混凝土拉拔试验数值模拟验证了其有效性。

A meso-scale concrete numerical model in three dimensions and a random generation algorithm of spherical aggregates are introduced.Based on the advantages and its superior docking to FEM software,Python is selected as the programming language to realize the generation procedure of aggregates,the validity judgement of geometrical parameters of aggregates as well as the establishment and meshing process of concrete structure.And the efficiency of this model is verified by a numerical simulation on pull-out test in reinforced concrete.
