It is shown that stress intensity solutions for axisymmetric cracks in thin-walled cylinders may be obtained for any prescribed axial stress distribution from plane strain solutions. This approach is illustrated by comparing solutions for internal circumferential cracks in several axial stress fields with numerical solutions for axisymmetric cracks. It may also be applied to external axisymmetric cracks.

Functionally Graded Layer

The objective of this study is to determine stress intensity factors (SIFs) for a crack in a functionally graded layer bonded to a homogeneous substrate. Functionally graded coating contains an edge crack perpendicular to the interface. It is assumed that plane strain conditions prevail and the crack is subjected to mode I loading. By introducing an elastic foundation underneath the homogeneous layer, the plane strain problem under consideration is used as an approximate model for an FGM coating with radial grading on a thin walled cylinder. The plane elasticity problem is reduced to the solution of a singular integral equation. Constant strain loading is considered. Stress intensity factors are obtained as a function of crack length, strip thicknesses, foundation modulus, and inhomogeneity parameter.
