Question
A component made of Aluminium 6061-T651 has an edge crack
with length equal to 15 mm, as shown
The yield
stress of the material is oy = 280 MPa and its fracture toughness
(Kic) ranges from 40 MN/m3/2 to 60 MN/m³/2
Consider now the same edge crack in a semi-infinite plate.
Determine the critical stress to avoid fracture.
