Problem 4. A large flat plate is subjected to constant-amplitude uniaxial cyclic tensile and compressive stresses. Compute the final critical surface crack length if the fatigue life must be a minimum of 7.0 x 10^5 cycles. Assume the initial maximum edge surface crack length of 1.80 mm and a maximum tensile stress of 160 MPa. Assume m = 1.8 and A = 7.5 x 10^-13 in MPa and meter units. Assume Y = 1.25.
Consider a steel plate with a through-thickness edge crack like the one shown in Fig. 6.21f. The plate width (W) is 75 mm, and its thickness (t) is 12.0 mm. Furthermore, the plane-strain fracture toughness and yield strength values for this material are 80 MPa m1/2 and 1200 MPa, respectively. If the application in which the plate is used is expected to cause a stress of 300 MPa along the axis perpendicular to the crack, would you expect failure to occur if the crack length a is 15 mm? Explain.
An Al2O3 specimen is being pulled in tension. The specimen contains flaws having a size of 100 µm. (a) If the surface energy of Al2O3 is 0.8 J/m2, what is the fracture stress?

Question: The tensile strength of brittle materials may be determined using a variation of Equation 9.1. Compute the critical crack tip radius for a glass specimen that experiences tensile fracture at an applied stress of 70 MPa (10,000 psi). Assume a critical surface crack length of 10–2 mm and a theoretical fracture strength of E/10, where E is the modulus of elasticity.
The Kic value of a steel is M within a square root of 186 MPa. If the stress to which the steel is exposed is 800 MPa, what is the maximum crack length that can be tolerated? (Take Y = 1.1)
Some aluminum aircraft components have a KIc = 35 MPa(m)1/2. It has been determined that failure occurs at a stress of 250 MPa when the critical internal crack length is 2 mm. Will this component achieve failure at a stress of 325 MPa when the critical internal crack length is 1.1 mm?
For a large plate, the geometry factor, f, is 1.03. Suppose a steel casting alloy has a critical fracture toughness of 78,886 psi*in1/2. The steel will be exposed to a stress of 40,295 psi during service. Calculate the minimum size of an edge crack that will grow. Repeat the calculation for Al2O3 with a fracture toughness of 1,600 psi*in1/2. How many times larger is the minimum size edge crack in the steel versus the alumina?
The part of the vehicle is production from an magnesium alloy ,if KIC 40 MPa√m. The fracture occurred at a pressure of 195 MPa when the maximum edge crack length was 3.0 mm. Calculate the value Y. If a stress level is increased to 275 MPa and the maximum edge crack length is reduced to 2.3 mm, predict whether any fracture will occur. Compare your answer with existing data. Justify your answer

Estimate the theoretical fracture strength of a brittle material if it is known that fracture occurs by the propagation of an elliptically shaped surface crack of length 0.20 mm and that has a tip radius of curvature of 0.001 mm when a stress of 1450 MPa is applied. The question is attached. The answer is not 29000. WileyPlus marks it as incorrect.
A plate with width w = 90 mm and thickness t = 5 mm carries a uniformly distributed tensile force P = 30 kN in longitudinal direction. The plate has an external transverse crack with length of 18 mm. To prevent sudden fracture, calculate the minimum required critical stress intensity factor (KIc) for mode I (in MPa.m1/2) for the plate material. Assume a safety factor of n = 2.4.
