Consider the following data for a range of materials. In which of the following situations is creep likely to occur? Melting temperature of various materials: Melting Temperature (°C Material Ti alloy 1668 Carbon steel 1375 Alumina 2070 Nylon 66 polymer 262 A carbon steel component under continuous load in a power station operating at 200°C. A nylon pipe carrying fluid at 125K. All of the scenarios. A Ti alloy in a turbine operating at 350°C. An alumina ceramic component in a furnace operating at 600°C.
A structural beam is built from steel with a yield strength of 345 MPa. The structure has a minimum service temperature of 5 oC, where the fracture toughness of the steel KIC = 60 MPam. What is the minimum surface crack lengths that must be detected by quality control to ensure that the full yield strength of the steel is available in the beam? Assume geometric parameter Y = 1 and plain strain conditions. Answer in millimeters.

QUESTION 14 A precipitation strengthened aluminium alloy has the following material properties: E = 75 GPa o = 450 MPa y K = 35.4 MPa m¹/2 C On inspection of a lightweight pressure vessel, a plate made from this alloy, with a width of 35 mm, is found to contain an edge-crack with a length of 3.5 mm during a regular maintenance inspection. Under standard operating conditions, this plate is subjected to a peak stress of 125 MPa. Estimate the critical crack length (ac) for fast fracture to occur under the applied stress. Give your answer in millimetres (mm) to an accuracy of two decimal places. Do not include the units 'mm' in your answer. Only give the numerical value. The stress intensity is given by the standard equation (K=Yona) where Y= 1.12 for an edge-crack in a semi-infinite width plate. πα
