The size effect of nominal ice failure pressure, fractals, self similarity and nonstationarity

The pressure-area curve shows that the observed ice failure pressure is proportional to the inverse square root of the loaded area. Two recent heuristic models for explaining this are compared and found to be modeling the same roughness profile, the self similar surface of fractal dimension 1.5, wit...
