    A theoretical analysis is presented for the membrane stresses around an elliptic hole in a long, thin circular cylindrical shell with the major axis of the hole inclined at an arbitrary angle to the axis of the shell. The analysis has been carried out for uniform normal internal pressure and axial tension. The method of solution involves a perturbation in a curvature parameter and the13; results obtained are valid, if the hole is small in size compared to the shell. A formula, from which the membrane stress concentration at the hole can be directly calculated, is presented. If one of the principal axes of the hole is parallel to the shell axis, it is found that for any state of biaxial stress in the shell, there exists a certain value of eccentricity of the ellipse for which the membrane stresses are constant all along the boundary of the hole.
