New materials developments have been significant, and recent developments based on computational methodologies allow the process to occur at a much faster pace. However, corrosion resistance is not yet among the properties being optimized (see the section on integrated computational materials science and engineering in Chapter 3).

The overarching vision of the committee is that corrosion research will be advanced further and faster when corrosion behavior is included along with other materials properties in modern science and engineering practice, as exemplified by programs such as Integrated Computational Materials Science and Engineering...

The Director of the Theory Department is Matthias Scheffler, born in 1951 in Berlin. He earned his PhD in Physics from the Technische Universitat Berlin in 1978 with a thesis written at the PHI on Theory of Angular Resolved Photoemisson from Adsorbates. His advisers were Kurt Moliere (PHI), Kyozaburo Kambe (FHl) and Frank Forstmann (Freie Universitat Berlin and FHl). Prior to his appointment as Director at the FHl in 1988, he was a staff scientist at the Physikalisch-Technische Bundesanstalt in Braunschweig. In 2004 he was appointed Distinguished Visiting Professor for Computational Materials Science and Engineering at the University of California Santa Barbara, where he spends up to a quarter of the year. 

The modern discipline of Materials Science and Engineering can be described as a search for experimental and theoretical relations between a material s processing, its resulting microstructure, and the properties arising from that microstructure. These relations are often complicated, and it is usually difficult to obtain closed-form solutions for them. For that reason, it is often attractive to supplement experimental work in this area with numerical simulations. During the past several years, we have developed a general finite element computer model which is able to capture the essential aspects of a variety of nonisothermal and reactive polymer processing operations. This "flow code" has been Implemented on a number of computer systems of various sizes, and a PC-compatible version is available on request. This paper is intended to outline the fundamentals which underlie this code, and to present some simple but illustrative examples of its use.

Von Mises stress is originally formulated to describe plastic response of ductile materials. It is also applicable for the analysis of plastic failure for coal undergoing high strain rate. The von Mises yield criterion suggests that the yielding of materials begins when the second deviatoric stress invariant J2 reaches a critical value. In materials science and engineering the von Mises yield criterion can be also formulated in terms of the von Mises stress or equivalent tensile stress, a scalar stress value that can be computed from the stress tensor ...

As we are going to show later in this chapter, computer simulations provide capabilities of solving problems which cannot be solved by theory or experiment, or even a combination of both. Let us start with asking how scientists and engineers approach physical systems. The question is fairly general, not even limited to materials science and engineering (MSE), let alone to polymer liquid crystals (PLCs). The answer is that one first describes the system, specifying the parts and their interactions, and then tries to make predictions what the system will do in the future under certain imposed conditions.
