PART-2 5) a. - Derive Griffiths' criteria for fast fracture in an ideal brittle material – using diagrams and explain the steps and assumptions made at each stage? (8 marks) b. Calculate the critical crack length for fast fracture for a Nickel alloy and a Sic ceramic with an applied tensile test of 250 MPa, in a Kic fracture toughness test. If these two materials are being considered for application as compressor blades in a jet engine, comment on the significance of your answers. -3/2 -3/2 Nickel Kıc = 60 MN m Sic Kic = 4 MN m (7 marks) = 6)
