A specimen of a 4340 steel alloy having_a plane strain fracture toughness of 45 MPa Vm (41 ksiVin.). is exposed to a stress of 1000 MPa (145,000 psi). Will this specimen experi- ence fracture if it is known that the largest surface crack is 0.75 mm (0.03 in.) long? Why or why not? Assume that the parameter Y has a value of 1.0. Questions Suppose that a wing component on an air- craft is fabricated from an aluminum alloy that has a plane strain_fracture toughness of 40 MPAVM (36.4 ksi Vin.). It has been deter- mined that fracture results at a stress of 365 MPa (53,000 psi) when the maximum internal crack length is 2.5 mm (0.10 in.). For this same component and alloy, compute the stress level at which fracture will occur for a critical in- ternal crack length of 4.0 mm (0.16 in.).
The flexural (or fracture) strength of brittle materials may be determined using a variation ofEquation 8.1. Compute the critical crack tip radius (row sub t in nm) for an Al2O3 specimen thatexperiences tensile fracture at an applied stress (sigma initial) of 275 MPa. Assume a critical surfacecrack length (a) of 2 * 10^-3 mm and a theoretical fracture strength of E/10, where E is themodulus of elasticity (393 GPa). Note, fracture will occur when sigma sub m reaches the theoreticalfracture strength of the material.given equation: sigma sub n = 2*sigma initial*sqrt(a/row sub t)
