The objective of this paper is to report on the research about the effects of the cylinder materials, the hoop-wrap materials and the crack size on all-metal cylinders and metal-lined cylinders with axially oriented internal cracks through comparisons of the fracture behaviors between the all-metal cylinders and the metal-lined hoop-wrapped cylinders. The three-dimensional finite element methods were used to model these different cylinders. The different fracture behaviors of these cylinders are presented by comparing the calculated normalized stress intensity factors and the crack-tip opening displacements of these cylinders. The effects of the crack sizes, the cylinder materials and the hoop-wrap materials on the crack driving forces are studied and discussed.
