Very thin torispherical pressure vessel ends under internal pressure: Strains, deformations, and buckling behaviour

Abstract

Test results are presented for seventeen stainless steel torispherical pressure vessel ends, of production quality, loaded to failure under internal pressure. The nominal thickness/diameter ratios covered were 0.00237, 0.00158, and 0.0019, and the series included both ‘pressed and spun’ (eleven) and ‘crown and segment’ (six) ends. Details of the elastic, post-yield and buckling behaviour are given, and, where appropriate, predictions and relevant data from other sources are included for comparison. The full set of results is discussed in detail.
