4. The drawing of the sample is not that important and a compact specimen is there in the notes (a) The stainless steel and polystyrene rulers in Example 5.2 are loaded as cantilevers of length 250 mm. Both have sharp transverse scratches of depth 0.2 mm, near the base of the cantilever on the tensile side. For this surface crack geometry, assume the factor Y in equation (8.4) is 1.1. The fracture toughness K1c of steel and polystyrene are 80...
