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.
