The nonlinear response and eventual collapse of a cylinder loaded by resultant external pressure and axial load is analyzed. The cross-sectional description of the cylinder is sufficiently general to include ovality, eccentricity, and local thickness anomalies. Applications of the model include the prediction of minimum collapse resistance of commercial tubulars.
