Computer realizations of crack trajectories for two case studies presented here seem to be in good agreement with experimentally observed ones. Procedure for simulation is relatively simple and straightforward once the input parameters (fractal dimension d and diffusion coefficient D) are known. However, sufficient number of repeated experimental tests is needed to extract these parameters. R EFERENCES [1] A. Chudnovsky, In: Studies on Elasticity and Plasticity, ed. L.
