A fractal dimension is an index for characterizing fractal patterns or sets by quantifying their complexity as a ratio of the change in detail to the change in scale: 1 Several types of fractal dimension can be measured theoretically and empirically () Fractal dimensions are used to characterize a broad spectrum of objects ranging from the abstract to practical phenomena, including .
A significant ‘scale effect’ is observed when sea ice forces on structures are measured at field scale: the force per unit contact area is not independent of area, but decreases with increasing area Fragments of broken materials are found to have a fractal size distribution, with a fractal .
