Consider a plate with a through-thickness crack subjected to a bilateral tensile stress and oriented at an angle β between the horizontal axis and the crack. Derive an expression for KI and KII for this configuration. What happens to each K when σ1 = σ2? Calculate K (Irwin correction) for a plate with a through-thickness crack of width 2W σ = 250 MPa; σγ = 350 MPa; 2W = 203 mm; 2a = 50.8 mm. Assume the following stress-stress intensity relationship. $K_{eff} = \sigma \sqrt{\pi a_{eff}} \left[ sec \left( \frac{\pi a_{eff}}{2W} \right) \right]^{1/2}$
