摘要
在细观层次上将混凝土看成是由骨料和砂浆基体组成的两相复合材料,讨论了混凝土力学性能的计算机模拟方法.按照骨料级配曲线和面积百分比,生成各种尺寸的骨料颗粒.应用蒙特卡洛方法将所生成的骨料分布到混凝土截面上.模拟结果表明,所生成的骨料分布图案与实际骨料分布十分相像.
Concrete is taken as a two-phase composite material consisting of mortar matrix and aggregate on mesoscopic level in the following discussion on a numerical simulation approach for dealing with polygonal aggregate distributions in concrete. Aggregate particles of various sizes were first generated for a given aggregate gradation curve and aggregate area fraction, and then distributed in a concrete intersection using Monte Carlo technique. Simulated results show that the generated aggregate patterns are very similar to the patterns of practical aggregate distributions.
