(15) An alloy steel sheet with a central crack was subjected to a uniaxial stress 40,000 psi when the sheet failed. If the plastic zone size was 0.01 inches just at the point of failure, what is the size of the crack present in this sheet? (oys = 60 ksi) If this sheet was 0.125 inches thick, was this the lowest value of fracture toughness that this material could have?

9) An aircraft component is made of an aluminum alloy that has a fracture toughness of 60MPavm. When a crack of 2.5mm exists in the component, the material fractures when a stress of 440MPA is reached. If a crack of 5.5mm exists in the material, what stress would need to be reached to cause failure?
Draw two schematic graphs using pencil showing a typical stress-strain curve for aluminum. The first graph should show engineering stress vs engineering strain, and the second graph should show true stress vs true strain. Label the showing: (i) elastic modulus (ii) proportional limit (iii) yield stress (iv)yield strain (v) fracture stress (vi) fracture strain on each graph. You may showboth graphs on one plot. Explain the difference between engineering stress and true stress.

1.) Assume that a wing component on an airplane is made of an aluminum alloy with a plane strain fracture toughness of It was found that when the maximum internal crack length is 2.5 mm, breakage occurs at a load of 365 MPa. Find the stress level at which a critical internal crack length of 5.0 mm will fracture for the identical component and alloy. 2.) An S-five ninety alloy specimen nine hundred mm long will be subjected to eighty MPa tensile stress at eight hundred and fifteen degrees celcius. Later after five thousand of hours, compute its elongation. Consider a sum of one point five mm in the both immediate and main creep elongations. - Please answer this 2 and indicate the givens.

A three-point transverse bending test was performed on a glass specimen having a square cross-section of 18.5 mm length on each edge. The specimen fractured at a load of 4530 N when the distance between support points was 42 mm. A second test is to be performed on another specimen of this same glass material, but one that has a circular cross-section. What minimum specimen diameter is required to ensure that fracture will not occur when a load of 3480 N is applied? Assume that the support separation is maintained at 42 mm. mm
