| 摘 要： | 混凝土在损伤演化期间所形成的微裂纹具有明显的自相似特征,即分形特征。研究表明,用分形理论方法可以定量描述和区分混凝土在损伤演化期间形成的极其不规则的微裂纹。通过分形理论中分形插值运算来构造迭代函数系统,并对其损伤裂纹进行了预测。结果表明,该方法对混凝土损伤裂纹的预测取得了较好的效果。

| Abstract: | The micro cracks of concrete that formed during the injury evolution have obvious self-similarity features,which are known as fractal features.The research shows that the fractal theory can be used to describe quantificationally differentiate and anomalistic micro cracks of concrete that formed in injury evolution.Iterative function system was constructed by fractal interpolation operation and the fracture cracks were predicted.The results expatiated that the method can predict efficiently the fracture cracks of concrete. |
