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. Singular spaces do not enjoy Poincaré duality in or

The contents of this book have therefore been carefully planned to provide both an introduction to the fundamental theory of material deformation simulation, and also a comprehensive survey of the "state-of-the-art" of deformation modelling technique

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.
