摘要: The Griffith criterion is rewritten to account for the propagation of a self-affine crack. It shown that stress-field singularity in close vicinity crack tip involves an exponent -(${\mathit{d}}_{\mathit{F}}$-1)/2 instead -1/2. Furthermore, fracture toughness be related ratio maximum height ${\mathit{z}}_{\mathrm{max}}$ correlation length \ensuremath{\xi}.
