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.

As requested by many junior researchers, the derivation of Gurson model and Gurson's original paper are attached below. This is part of test by Prof.Wang(http://www.matsceng.ohio-state.edu/faculty/wang/) to me last year.
