分形几何方法模拟混凝土材料的裂纹扩展

A Fractal Kinked Model for Simulation of Cracks Development of Reinforced Concrete Material

假设裂纹顶端沿分形轨迹运动，开裂路径垂直于最大主应力方向，由此建立了描述裂纹非规则扩展的分形几何模型．给出了用Ｃ语言开发模拟混凝土简支梁在集中荷载下裂纹生成与扩展的例子．

This paper presents a fractal kinked model for simulation of the cracks development in reinforced concrete elements with the assumption that the cracks always develop along the fractal orbits and are vertical to the direction of the maximum main stress. An example on simulation of cracks development of a simple concrete beam with a concentrated load is given.
