A mechanical component is fabricated from a metallic alloy. From the experiment, it is obtained that the fracture of this material occured at a stress of 36 ksi when the maximum internal crack length is 0.10 in. The plain strain fracture toughness of this material is 30 ksi sqrt(in) for this same component and alloy, investigate whether fracture will occur at stress level of 55 ksi when the internal crack length is 0.06 in.

For a cylindrical S-590 specimen (Animated Figure 8.33) originally 11 mm in diameter and 548 mm long, what tensile load (in N) is necessary to produce a total elongation of 2.0 mm after 1500 hours at 815°C? Assume that the sum of instantaneous and primary creep elongations is 0.73 mm. N [The tolerance is +/- 5%.]
A tie rod made of quenched and tempered 4340 steel is used as a critical linkage in an industrial apparatus. The rod is subjected to an alternating cyclic tensile/compressive stress from 550 MPa to -550 MPa. An inspection of the rod revealed a 3.5 mm deep edge crack on the surface of the rod. Please answer the following question for the rod given the properties in the table and curve below and fracture toughness of 55 MPa√m. (NOTE: Y=1.12 for edge crack and use “a” not “2a” for the length of the crack) 1. What is the minimum crack size that would cause instantaneous fast fracture at the current maximum axial tensile loading, assuming plane strain conditions apply? If the resolution limit of the flaw detection apparatus were 1.5 mm, would this flaw be subject to detection? Show calculations to back up your conclusions.
