✦ Synopsis

Finite element analysis was performed on isotropic and orthotropic cylindrical shells with circumferential cracks. Two different types of loading boundary conditions were used which assume either the application of axial tension or torsion. Particular attention was given to the problem of transverse shear deformation which occurs around long circumferential cracks in thin-walled cylindrical shells under the loading conditions assumed. The effect of orthotropy ratio was investigated with E,,/Ez2 ranging from 1 to 49. It was found that the deformation is highly dependent upon the elastic properties, cylinder geometry and loading boundary conditions.
