A 65.4 mm wide aircraft inspection panel is made of 7074-T651 aluminium alloy. The material properties are: Fracture toughness, Kc = 25.8 MN m-3/2 Yield stress, oy = 505 MPa Following inspection, an edge through-crack of length 6.4 mm is found. During flight, this plate is subjected to a cyclic stress of 90 ± 30 MPa. Calculate the number of cycles to failure (N₁) using Paris' Law and the material constants (in their standard units): A = 1.2 x 10-¹2/m = 2.8 A 65.4 mm wide aircraft inspection panel is made of 7074-T651 aluminium alloy.
