dc:description "Assuming a linear geometric transformation of the crack and a crack-propagation condition at the flawless network's strength, the failure stress follows a scaling law in χ like LEFM's but with one parameter C describing tip blunting; a least-squares fit gives C = 1.102 and matches the simulations far better than LEFM.";

(2), but features an unknown parameter C that effectively describes the geometric change of the blunted crack tip under elastic deformation.
