摘要: To study multi-fractal behavior of corroded steel surface, a range fractal surfaces Q235 were constructed by using the Weierstrass-Mandelbrot method under high total accuracy. The spectrum surface was calculated to characteristics W-M surface. Based on shape feature least squares applied quadratic fitting function quantitatively analyzed simplify calculation results showed that fitted well with curve fitting, and evolution rules trends forecasted accurately. findings can be research mechanisms formation provide new approach for establishment corrosion damage constitutive models steel.
