Question
The fuselage of an airliner can be considered as a thin-walled tube
internally pressurized with a diameter of 7 m and a thickness of 3 mm. It is made with
Aluminum sheets with K ic fracture toughness of 100 MPa m
1/2. At cruising altitude
internal pressure gauge shows 0.0.Mn/m2
.
. In a horizontal row rivets have been
caused many fatigue cracks and have joined together to form a longitudinal crack that
it goes through the thickness of the fuselage. Estimate the critical length for this crack to propagate,
causing the fuselage to break. (The pressure in a tube is resolved into a tension in the wall
from ? = p r / t, where p = pressure, r = radius, t = thickness
