An economically rational selection of submarine hull materials
An economically rational selection of submarine hull materials
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.

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.
