Nowadays, we often use the tools of computational analysis in engineering design. For the results of such analyses to be believable, the tools that are used have to pass rigorous tests. There are two categories of tests involved:

As a moderator here on iMechanica, I have deleted a few posts recently that were clearly spam. As iMechanica grows and becomes more visible within the mechanics community and the broader internet community, we can expect the frequency of these kinds of posts to increase.

The Rankine-Hugoniot equation governs the behaviour of shock waves (node/1245#comment-2327) normal to the oncoming flow.

Equations of State

An equation of state is a formula describing the interconnection between various macroscopically measurable properties of a system.

In physics and thermodynamics, an equation of state is a relation between state variables. More specifically, an equation of state is a thermodynamic equation describing the state of matter under a given set of physical conditions. It is a constitutive equation which provides a mathematical relationship between two or more state functions associated with the matter, such as its temperature, pressure, volume, or internal energy. Equations of state are useful in describing the properties of fluids, mixtures of fluids, solids, and even the interior of stars.

USNCCM Invited Session: Stress Evolution at the Nanoscale

Submitted by Edmund B. Webb III on Fri, 05/04/2007 - 23:48

conference

The U. S. National Congress on Computational Mechanics will be held in San Francisco, CA July 23-26 2007 (see link for conference below). As part of the symposium, "Modeling and Simulation of Nano Materials and Mechanics", an invited session discussing stress evolution at the nanoscale will be held. This session will foster discussion of outstanding computational challenges to understanding and predicting stress evolution during growth of materials at the nanometer length scale. Registration information for the meeting can be found via the link below.
