Johan Blaauwendraad,Jeroen H. Hoefakkerimulation of a kinetic energy penetrator versus a titanium target, the failure of which was considered to be plugging due to high strains..This paper discusses the modifications involved, the results of the tests performed and the extrapolation of techniques to handle other failure mechanisms, plane strain simulations, and multi-target situations.

Johan Blaauwendraad,Jeroen H. Hoefakker types described in this report should serve as a standard of comparison for large scale computations of penetration phenomena. These data are already being used to guide development of improved engineering models for long rod penetration.

Structural Stability and Vibration a backward heat equation, but the numerical calculations remain stable (convergence is not so clear); u. jumps into neighboring regions where σ’ > 0. We reproduce in a simple form the Brezis-Ekeland variational principle for the heat equation, and we follow Nohel in speculating on its convexification for a law that has a “softening range” σ’ < 0.

Towards a Revival of Natural Philosophyd (iv) large-scale computing hardware and software. In this article, primary emphasis is directed toward problems in blast wave hydrodynamics and in penetration mechanics (although other applications could include radiation transport, plasmas, laser interactions, structural response, combustion, etc.) which have the following common features:
