PRESSURE VESSEL DESIGN CRITERIA

Abstract

The purpose of the work being performed in this program was to provide experimental data to assist in establishing material selection and design and fabrication criteria for reliable, highly efficient pressure vessels. Preliminary values of ductility of 4340 steel were obtained from fracture strain measurements of narrow-bend and wide-bend specimens, and reductions of useful strength of offset tensile specimens were measured at several nominal strengths. Correlation of the reduction of wide bend fracture strains with the reduction of useful strength of offset tensile specimens at increasing nominal uniaxial strength levels was indicated. The 4340 steel under consideration exhibited higher ductility, both in the uniaxial and biaxial stress states, than had been anticipated from previous tests.
