Some topics on instructional design and technology may benefit iMechanica.

One of the mission statements of iMechanica is to use the Internet to enhance communications among mechanicians. It seems that the top three uses of the Internet among many of us are

• Emails
• PDF
• Google search 

It might be useful, and fun, for us to share the experience with these and other tools associated with the Internet.  I'll start a list of tools that I have found exceptionally useful.  All these tools are free of charge.

I am new to parralel computing and trying learn basic. wat are the languages can we use for coding in parallel computing. Can any one give me an example for this. Any resource link will do?

Tks in advance

In small strain elastoplasticity we start off with an additive decomposition of the total strain into elastic and plastic parts. In terms of strain rates we write

Prior to 1990 most large deformation plasticity algorithms extended this idea by postulating an additive decomposition of the Eulerian stretching tensor (rate of deformation):

ASEC 2008 is a two-day conference scheduled for midway through 2008 directed at structural engineers. This conference is a time out, providing an opportunity for like minded people to meet, share ideas and broaden their technical skills.

Some of you probably work on problems that involve moderately large strains. An useful strain measure for such problems in the logarithmic or Hencky strain. In particular, if you deal with the numerics of large strain simulations, you will often need to compute the material time derivatives of logarithmic strains.

Coated nanoparticles, which have a core-shell structure, have many applications. The attached manuscript shows some of our progresses in investigating the induced torque and orientation of such nanoparticles in an electric field. We show that the shell of a nanoparticle has an important effect on its orientation, even when the shell is thin and takes only a small portion of the total volume. For instance, a thin layer coating of highly conductive Au can dramatically change the induced torque on a SiO₂ or TiO₂ nanoparticle.
