Strength of material

(See attached file for full problem description with equations and diagram) --- Practice problem for Fracture and Fatigue. Adapted from S. Suresh, Fatigue of Materials, second edition, Cambridge University Press Publishing. Consider an aircraft fuselage, existing like a cylindrical pressure vessel. Every day, this aircraft takes 6 flights, and each time, the fuselage is pressurized to a  (This means the pressure DIFFERENCE between the inside and the outside.) The radius of the fuselage is . The fuselage skin is made of an aluminum alloy with thickness . Thus, you should all be able to calculate the hoop stresses in this system. Now assume that a crack of width exists... click for more
