Eighteen pressure vessel heads having nine different geometries and made from two different steels were subjected to monotonically increasing external pressure until collapse occurred. Deflection of the crown and strains in the most highly strained regions of the concave side of the heads were recorded as functions of pressure. All heads underwent permanent deformations. Four modes of failure were observed: symmetrical buckling of the crown, asymmetrical buckling in the knuckle and transition region, asymmetrical buckling of the cylindrical wall, and progressive deformation without buckling.
