Derivative of Logarithmic Strain

Submitted by Biswajit Banerjee on

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.

Orientation of Core-Shell Nanoparticles in an Electric Field

Submitted by Wei Lu on

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.

Looking for a copy of Bridgeman's classical work, "Studies in Large Plastic Flow and Fracture"

Submitted by Zhigang Wei on

I found it's hard to get copies of some old but classic works. Those classic works usually represent the most important findings in corresponding fields. Though thousands of new articles are published every year with easy online access, more than 90% of them will not be touched by anybody after 10 years. It's a pitty to see, however, there's no easy access to most classic old works in almost every fields.
