We have theoretically analysed the perimeter-area relation and simulated its application to measuring the fractal dimension of fracture surfaces. It is proved that the fractal dimension D obtained by slit island method (SIM) is related to the dependence of measured area A(delta) of the slit island on yardstick delta. So in some cases, the dimension D obtained by SIM is dependent on yardstick and in other cases independent on yardstick delta. But in all cases, when delta-->0 the dimension D obtained by SIM approaches the real fractal dimension (similar dimension) of 'coastline' of the island. We analysed some experimental data and found some new and interesting characteristics of crack propagation in steels.

Using a fractal model, we give a new interpretation of the reversed sigmoidal curves of fracture surface profile length obtained in some experiments. It is pointed out that a single parameter (fractal dimension D) is not sufficient to characterize a fractal curve completely. It is shown that the initiator length L-0 is also important to characterize a fractal curve. We have derived a formula which correlate the fracture energy with the fractal parameters of the fracture surfaces and analyzed some experimental data.
