Hello All. This is my first blog entry in iMechanica!. This post is about my new paper with Prof. Amine Benzerga entitled "A constitutive model for plastically anisotropic solids with non-spherical voids", accepted for publication in JMPS (URL: http://dx.doi.org/10.1016/j.jmps.2010.03.007 ). In case you are not able to view the online version, a preprint of the paper is attached. This paper should be of interest to anyone working in the ductile fracture area. Your comments and feedback are welcome.

what are the books/papers that give the basic idea about dislocation-crystal plasticity theory?

Dear Colleagues：

I am very happy to let you know that our innovation of material like snail shell has been selected to be presented at EXPO 2010 in Shanghai at Youth Innovation Center (中国2010年上海世博会全球青年创新之旅).

I am working on an analytical solution for a  crack propagation  problem in a porous media using complex variable methods. Does anybody know some good references?

Graphene edges, analogous to the structure of nanotubes, can significantly influence the overall electronic and magnetic properties of graphene nanostructures, and thus have become important issues in graphene research, especially for electronic applications. In this recent paper published on PRL, we reported that the free folding of suspended graphene sheets by random mechanical stimulation has preferred folding directions.

Phanish Suryanarayana, from the California Institute of Technology, is the 2010 Melosh Medalist for the Best Student Paper in Finite Element Analysis.  Phanish won for his paper titled "Non-periodic Finite-Element and Mesh-Free Formulation of Kohn-Sham Density Functional Theory".  He presented the paper on Friday, April 30, 2010, on the campus of Duke University.  

Please join me in congratulating Phanish!
