Description/Abstract

The selection of an external pressure vessel material is described. Failures in the rupture and buckle modes are discussed, as well as the problem of submarine hull hydrostatics. A spherical geometry admits simplification to allow focus on the economic problem. The economic cost function is comprised of 28 variables: the market prices of the alloy components, some material properties of the alloy, and various extrinsic data. A variant of the exhaustive search method was preferred due to the discontinuous nature of the price data. A large database of alloys is searched, preliminary results obtained for a selection of 19 AISI alloys in the 300 and 400 series, and conclusions drawn.
