采用经典的Mandelbrot分形模型、Underwood修正分形模型和分维谱模型对三种球墨铸铁断口的分形特性进行了研究,并应用于铸态球铁拉伸断口的断裂过程和断裂机制分析.
The fractal characteristics of the three kinds of ductile iron fractures were studied by classical Mandelbrot fractal model, Underwood modified fractal model and fractal dimension spectrum model, and applied to the fracture process and fracture mechanism of cast ductile iron tensile fracture.
