Thesis (M.A.Sc.)--Carleton University (Canada), 2008.

In this thesis, the fracture behavior of a hollow cylinder with internal circumferential crack under uniform tensile loading is examined. Complete finite element analysis of the cracked cylinder is conducted to determine key fracture parameters such as K, T-stress, and J-integral. The finite element method is used to determine these fracture parameters using both linear elastic analysis to obtain K and T-stress and elastic plastic analysis to obtain fully plastic J-integral. The cylinder thickness ratio studied is ri/ro = 0.2, 0.4, 0.6, and 0.8 with crack depth ratio of a/t = 0.2, 0.4, 0.6, and 0.8. The fracture parameters are applied to conventional and constraint-based failure assessment diagrams to determine the maximum load carrying capacities of the cracked cylinders. The fracture mechanics parameter solutions of T-stress, J-integral obtained and the constraint-based failure assessment procedures demonstrated in this thesis will enable a more realistic fracture assessment for circumferentially cracked hollow cylinders.
