Fig. 12: Stress intensity factors calibration.

From: Principle of local symmetry in mixed-mode fracture

Fig. 12

Panel a shows a scheme of the coin-shaped fracture model under tensile loads (σ = 1 Pa) and shear τ (for simplicity, τ = σ). Not to scale for clarity. The angular displacement along the fracture is given by θ. Panel b shows the representation of the stress intensity factors K (where subindex I, II, and III represents modes of deformation I, II, and III) as obtained by Eq. (6) (lines), and the result obtained from finite element analysis (symbols). In the calculations we use the Poisson modulus ν = 0.43, the dimensions of the cube L = 10 cm, and fracture radius a = 1 cm.
