Ps. Theocaris et Pd. Panagiotopoulos, THE FRACTAL ASSUMPTION IN CRACKS - BILATERAL CALCULATION METHODS, International journal for numerical methods in engineering, 36(9), 1993, pp. 1597-1604
The paper considers the fractal nature of cracks by assuming the fract
al as the fixed point of a given transformation. This concept enables
the study of a sequence of classical-geometry crack problems whose lim
it gives the solution of the fractal-geometry crack problem. The metho
d is illustrated by a numerical example. It was shown that the fractal
nature of the cracks influences the value of the stress intensity fac
tors.
