Abstract : Buckling and initial postbuckling of an oval cylindrical shell under pure bending and under combined uniform axial compression and bending is investigated. The first and second order stability equations are developed from the Donnell-type equations which are shown to be appropriate. The solution of these two sets of equations determines, respectively, the buckling characteristics and a 'sensitivity parameter'. The buckling loads are found to be in good agreement with the engineering approximation based upon the assumption that buckling occurs when the local axial stress equals that corresponding to the classical buckling stress of a locally equivalent circular cylindrical shell under uniform axial compression.
