WebNov 1, 2024 · Using the numerical model presented in Sections 2 Application of graph theory to fracture networks, 3 Numerical model, the HF networks in the fractured reservoir are shown in Fig. 7.Note that most of the HF paths propagate along the pre-existing NFs because NFs are usually weak planes (Zhou et al., 2008, Zhou et al., 2010).All of the NF … The traditional approach to the design and analysis of a part is to use strength-of-materials concepts. In this case, the stresses due to applied loading are calculated. Failure is determined to occur once the applied stress exceeds the material's strength (either yield strength or ultimate strength, depending on the … See more In fracture mechanics, a stress intensity factor is calculated as a function of applied stress, crack size, and part geometry. Failure occurs once … See more The theoretical value of stress at the tip of the ellipse is given by: where σ is the nominal stress and ρ is the radius of curvature of the ellipse, ρ=b2/a. where a is the crack size and Y is a dimensionless geometry factor that … See more Fracture mechanics is important to consider for several important reasons: Because the concept of the stress intensity factor … See more As the radius of the crack tip approaches zero, the theoretical stress approaches infinity. This infinite stress is known as a stress singularity and is not physically possible. Instead, the … See more
