Dear Mechanicians,
Recently I have seen many researches on the crystal plasticity, Could someone tell me some basic difference between classic plasticity and crystal plasticity ?! and what is the crystal plasticity theory for ?
Thank you very much
Best Regards
A video that shows how some common couplings work. It's an advertisement but interesting nevertheless. Does anyone know how the Thomson coupling works and what its main drawbacks are? It seems a bit complex and will probably have a higher rate of failure than simpler geometries - but maybe not?

On 6 June 2007, about 50 mechanicians attended a special session at the McMat 2007, "iMechanica.org get together". The attendees of this special session came from various job sectors, such as academia, industry as well as government agencies. The session was chaired by K. Ravi-Chander and Rui Huang, who also served in the organizing committee of McMat 2007.
The 2007 Maurice A. Biot Medal for Poromechanics has been awarded during the ASCE Engineering Mechanics Conference held at Virginia Tech last Tuesday.
The 2007 Biot Medal winner is Dr. James R. Rice of Harvard University.
If you are interested in further information, such as citation of Dr. Rice's work, and photos, you can check this page:
Hi, I am a newcomer. This is a nice place. a lot of useful information.
I have attached a copy of my McMat07 talk below. The talk is about a modified mechanical threshold stress (Follansbee-Kocks) model that can be used for strain rates > 1000 /s and high homologous temperatures. In the model, the pressure dependence of the flow stress arises from the pressure dependence of the shear modulus. Even after using the most accurate models for the shear modulus (and the melting temperature) we find that the pressure sensitivity of the flow stress is underestimated by our model (by quite a bit).
Here is an e-book on Engineering Fracture Mechanics ; you can also download a demo version, the preface, and other related stuff from the page. The idea of the book (as described in the page) sounds interesting:
