摘要:
在提出一种交叠骨料微步长迭代自动调整算法的基础上,采用任意凹凸型骨料配置算法建立混凝土细观数值试件。基于细观单元的弹性损伤本构关系,采用位移控制模式,着重针对两类常用的力学参数随机分布——Weibull及对数正态分布,进行了不同力学参数的常规混凝土拉压数值模型破坏试验,分析了主要力学参数的随机分布对混凝土试件宏观表征力学性质的影响。该研究可为混凝土细观数值模型中力学参数的合理确定提供依据。
Abstract:
According to the objective grading curve and filling area fraction of aggregates, numerical concrete specimen was firstly built on the basis of the advanced numerical generation method of aggregates with random shapes. And then, mesoscopic numerical simulation tests were carried out to study the damage evolution and to compare the influences of mechanical parameter distribution patterns(Weibull and lognormal distribution)on the mesoscopic strength of concrete specimen. Numerical result shows that Weibull distribution pattern is more active to reflect the discrete mechanical properties of concrete.
