Submitted by Anonymous (not verified) on

Katia Bertoldi, of Harvard University, has graciously accepted our invitation to be Editor of the iMechanica Journal Club. Katia has a knack to organize really interesting and inspiring symposia and workshops.  Here are two examples:

Extreme Mechanics: Elasticity and Deformation.

The New England Workshop on the Mechanics of Materials and Structures.

3-D crack propagation using 2-D dimensional finite element

Submitted by psubbu2000 on

Dear Friends,

     I have developed a ser of 2-D finite elements for the problems of structural mechanics. These two dimensional elements are capable of accurately predicting three dimensional stress states using three diemnsional constitutive law. My doubt is: can these elements be used for the analysis of 3-D crack propagation using XFEM?.  The displacements chosen for these elements are simple.

Multiple-Stripe Lithiation Mechanism of Individual SnO2 Nanowires in a Flooding Geometry

Submitted by Jianyu Huang on

PRL 106, 248302 (2011)     The atomic scale lithiation mechanism of individual SnO2 nanowires in a flooding geometry was revealed by in situ transmission electron microscopy. The lithiation was initiated by the formation of multiple stripes with a width of a few nanometers parallel to the (020) plane traversing the entire wires, serving as multiple reaction fronts for later stages of lithiation.
