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
