The Micromechanics of Materials group at the Zernike Institute for Advanced Materials in the Netherlands is looking for a qualified PhD student to unravel irradiation-induced embrittlement in nuclear materials. A detailed description can be found in the attachment. Ideally, candidates have an MSc degree in mechanical or nuclear engineering, (applied) physics, material science or a related field, but holders of a BSc with the highest ranks may also be considered.

Apply before it's too late: June 1. 

Failure of railway axles has been the problem which gave origin to the studies about 'fatigue'. The modern approach to the structural integrity of these safety components is to complement the traditional designwith a 'damage toleranc' analysis.

Hello all,

Last year when I started implementing interface elements to model material failure, I realized that the formulation is easy except how to generate a mesh with interface elements. I did a googling to search for such a free program. Amazingly, I did not find any although there are many researchers working on the fracture mechanics field.

So, I wrote a small object-oriented C++ program which reads a FE mesh, duplicates nodes and insert interface elements where asked. The program is able to

(1) insert 1D/2D interface elements everywhere in a FE mesh

APS March Meeting Focus session: "Tribophysics: Friction, Fracture and Deformation Across Length Scales"

March 21 - 25, 2011, Dallas, Texas
Details at http://www.aps.org/meetings/march/scientific/focus2.cfm#12.7.3

Invited speakers: Michael Marder (Univ. of Texas); Julia Greer (Caltech)

Organizers: Robin Selinger (Kent State), Jacqueline Krim (NCSU), Noam Bernstein (NRL)

I will be teaching a sophomore level class  mechanics of materials class.  The class will cover mechanics of basic strength of materials (e.g. beams, pressure vessels), but I also want to teach basic elements of failure mechanics (fracture, fatigue, plasticity, and wear.)  I'm looking for a recommendation of an undergrad mechanics textbook that covers the fracture, fatigue, plasticity, and wear.  The students will have had a statics and mechanics class and their textbook already covers strength of materials.  Thanks.

During charging or discharging of a lithium-ion battery, lithium is extracted from one electrode and inserted into the other.  This extraction-insertion reaction causes the electrodes to deform.  An electrode is often composed of small active particles in a matrix.  If the battery is charged at a rate faster than lithium can homogenize in an active particle by diffusion, the inhomogeneous distribution of lithium results in stresses that may cause the particle to fracture.  The distributions of lithium and stress in a LiCoO2 particle

Dear iMechanica commmunity,

we are looking for 3 PhD students at Oxford, starting from the 1st of October 2010 or as soon as possible thereafter. The closing date for the application is the 26th of July. The 3 students are required for two different research projects, namely:

1) Underwater blast on composite structures - open only to EU nationals; 2 PhD students are required. The studentships are advertised here

A PhD position is available at Centre Henri Tudor (Luxembourg) and Cardiff University (UK) on the simulation of crack propagation with adaptive extended finite element methods.

Candidates from any country are eligible. 

Please contact me for details.

I welcome and encourage all my fellow imechanicians to participate in the international conference being organised at Thapar university patiala,  punjab, india during november 2010.

The details regarding the conference and research paper format are attached.

I saw this on Science Daily, anyone knows ?

A fully funded PhD position is immediately available in the area of multi-scale modeling of geomaterials within the research project "Failure of cohesive geomaterials: bridging the scales - GEOBRIDGE" at Laboratoire Sols, Solides, Structures - Risques (3S-R), Université Joseph Fourier, Grenoble, France.

I attach Barenblatt's paper which is difficult to access. The paper includes a milestone idea of the cohesive surface that  allows us to get rid of unphysical singularities in the older formulations of fracture mechanics.
