Determine the modulus of toughness
WebThe results presented in the paper are related to the prediction of the effective fracture toughness of particulate composites (KICeff). KICeff was determined using a probabilistic model supported by a cumulative probability function qualitatively following the Weibull distribution. Using this approach, it was possible to model two-phase composites with an … WebFormations with low Poisson's ratio, low fracture toughness, and high Young's modulus are typically the best candidates for slick water hydraulic frac. Fig. 13.2 shows the schematic of a sample under vertical stress and therefore changes in length and width of the sample that can be used to calculate the Poisson's ratio as described in Eq.
