Welcome to the February 2009 issue. In this issue, we will discuss the use of finite elements (FEs) in quantum mechanics, with specific focus on the quantum-mechanical problem that arises in crystalline solids. We will consider the electronic structure theory based on the Kohn-Sham equations of density functional theory (KS-DFT): in real-space, Schrödinger and Poisson equations are solved in a parallelepiped unit cell with Bloch-periodic and periodic boundary conditions, respectively.

Why do we often use Jaumann rate instead of Truesdell rate?

Submitted by Rong Tian on

In the attachment, we show that Truesdell rate can by simplified to Green-Naghdi rate by assuming F .=. R and can be further simplified to Jaumann rate by assuming W .=. R(.)R(T), where .=. means approximately equal

In a stretch dominant deformation, the three rates give different stress rate. This is usually explained by that we need a different tangential modulus for different objective rate. However, it is hard to understand why we need to change "material" modulus when we use a different "mathematical" form of objective rate as they are all supposed to be equivalent.

TWO MECHANICAL ENGINEERING FACULTY POSITIONS IN CHILE

Submitted by Ramon Frederick on

The University of Chile invites applications for two full time faculty positions in Mechanical Engineering. Applicants must have deep interest in undergraduate and postgraduate teaching, as well as the purpose to conduct long term, externally funded research programs at international level. Candidates are also expected to maintain fruitful work relationships with industry in their respective areas. According to qualifications, they may be ranked at the Assistant or Associate Professor level. Candidates are sought in two areas:

  1. Energy: Research interests in conventional or alternative energies, with emphasis in energy conservation, generation or efficient use.
