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 athttp://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.

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 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.

I am teaching Subsea Integrity for the MSc students majoring in Subsea Engineering at the School of Engineering, University of Aberdeen. This is a course that combines the fundamental principles (corrosion, fracture, fatigue and material selection) with the industry applications (subsea integrity management and implementation, cathodic protection, case studies on subsea reliability and engineering assurance).

there are two analytical concepts that are very important in fatigue failure.the first one is crack closure and the others is residual stress .the first one is in behind of crack and the other emphasis in the front of crack tip. the question is if we use some devices such as AFM/SEM is it possible we model the energy filed during fatigue process? if this idea can be investigated the second question can be asked: is there any similarity to model for different loading conditions?

I appreciate if you also put your comment in my idea?

Bes Regards,

Hi all,

Can Hydrostatic stress be used as a fracture criteria? If so can critical hydrostatic stress be found experimentally? Thanks.
