A machine component is made of Aluminium alloy having an ultimate tensile stress
Ou = 350MPa, a fracture toughness Kic= 40 MPa√m and a geometry factor Y=1.12.
The component is subject to cyclic tensile stress of 200 MPa and cyclic compressive
stress of 70 MPa. Before the operation, using an ultrasonic non-destructive testing
technique, it was found that there is an edge crack of length 2mm. The crack growth
