The solid is described using the Born model on an FCC lattice with a starting notch. We obtain a value of the roughness exponent ζ≃0.5 in agreement with the value measured in microfracturing experiments. Our result supports the idea that at small length scales the fracturing process can be considered as quasi-static, which is the basic of the possible application of the model of line depinning to the case of fractures. date: 2000-05 date_type: published publication: Physica A: Statistical Mechanics and its Applications volume: 280 number: 1-2 publisher: Elsevier pagerange: 161-165 id_number: 10.1016/S0378-4371(99)00633-0 refereed: TRUE issn: 0378-4371 official_url: http://dx.doi.org/10.1016/S0378-4371(99)00633-0 citation: Parisi, Andrea and Caldarelli, Guido Self-affine properties of fractures in brittle materials.
