Question: 4a with the material listed above which material should be...

Question details

4.a) With the material listed above, which material should be used in the aerospace application of the i) fuselage, ii) high pressure and high temperature region of the aero-engine and iii) the air intake low pressure prop- fan of the aero-engine. Briefly explain why those materials are selected. b) Figure 1 shows the structure of a car. Only using the first four materials listed in Table 1, brief explain which material should be used for the following automotive structures: i) A-frame reinforcement, ii) Front side reinforcement, iii) Rear side member, iv) Bumper beam. A-frame reinforcement Bumper Beam Roof bow B-pillar reinforcement Front side members Floor side reinforcement Sil inner Rear side member c) With reference to DP 600 and TRIP 800, operating temperature of 30 deg C, ambient temperature of 20 deg C, operating strain rate of 100 s-1 and reference strain rate of 1 s-1, determine the energy required to induce plastic strain at 0.5 and 1.0 and comment on the results. (Note: do not need to consider the energy required to induce elastic deformation.)
