J. M. Alexander, a method of Thom constructs characteristic homology classes using the bordism invariance of the s- nature. These classes are not in general homotopy invariants and consequently are ne enough to distinguish manifolds within the same homotopy type.

Finite-Element Analysis of the Superplastic Forming of Thin Sheet Componentsealized. Superplastic forming (SPF) can be used to forge solid components such as turbine discs and die moulds or alternatively to blow form thick and thin sheet components. This chapter will be concerned with thin sheet forming.
