You are the Lead Design Engineer in charge of developing the wing of a new military fighter jet. After an exhaustive materials selection analysis, you have determined that 6/4 Ti alloy (Ti with 6% Al & 4% V) will best meet the needs of this application, due to its excellent toughness, elastic modulus, and yield strength (23.6 kN/m, 115 GPa, and 1450 MPa, respectively). a. As part of the design process, you have been asked to specify the maximum stress the skin of the wing can withstand, based on recognition of the fact that, once in service, the minimum flaw size that will be detectable by NDT will be 1 mm. b. Based on your analysis, will this be the most desirable design with regard to safety? If not, why? Be sure to clearly state any assumptions made in your analysis.
