fracture mechanics

POSTDOCTORAL RESEARCH ASSITANT – HYBRID SOLAR PANEL The Department of Civil Engineering and Engineering Mechanics at Columbia University seeks applications for a position as a Postdoctoral Research Assistant. A Postdoctoral Research Assistant is a junior level research position and works under the supervision of a faculty member in the department.

Hi everyone,

    I am not a student majoring in the mechanics. But I have found that: the element eroding method is so powerful in numerical simulation (i.e. using ls-dyna) if we reduce the mesh size, then we can get a very perfect fracture process of material. So why we need fracutre mechanics?

I am working with shape memory alloys (nitinol), and am in that respect investigating fracture behaviour of NiTi, using, among other things, simulations in ABAQUS. ABAQUS doesn't have a material model that include plasticity unless you pay for it. I am wondering if anyone have implemented either of the following models as a UMAT, and if you are willing to share the code with me.

The models I am interested in are:

hi all,

 I am a mechanical engineer currently pursuing Master degree (Post graduation). Ultimately i also want to pursue a research leading to PhD after my master's. Its my burning desire to do some significant research in the field of Fatigue analysis using Fracture mechanics approach preferably for aerospace domain using advanced CAE softwares like Nasgrow, Afgrow, Abaqus, FE-safe, MSC Fatigue, etc,..

Dear Colleague,
the IV European Conference on Computational Mechanics-ECCM 2010, Solids, Structures and Coupled Problems in Engineering, organized by ECCOMAS, will take place in Paris, France, May 16-21 2010 (see the Congress website http://www.eccm2010.org/  for more information).
During this conference, we are organizing a Minisymposium entitled: 

Hi all,

I am currently working on mooney-rivlin materials. I wonder if someone have tried to compute GI, GII and GIII with the EDI because I don't understand how to compute WIII with mooney-rivlin.

Thanks a lot

I was wondering what are the advantages of damage mechanics and fracture mechanics over each other? Specially in order to model the delamination phenomenon.

The Ruhr University Bochum, Germany, invites applications for a PhD / PostDoc position at the Interdisciplinary Centre for Advanced Materials Simulation (ICAMS).

Dear all,

Just in case it is of interest to some of you, we provide links to three postprints related to our Abaqus implementation of the X-FEM. The latest is an "article in press" in Eng Frac Mech where we explain the essentials of the implementation and provide a link to the source code for the Abaqus computation. Note that the implementation is limited to 2D and the pre-processing code needed for element subdivision is not provided.

Composite Vehicle Research Center (CVRC) at MSU has an immediate opening for a postdoctoral research associate to conduct research in non-destructive evaluation (NDE) and structural health monitoring (SHM) of composite materials in an effort to develop self-diagnostic composite structures for air and ground vehicles.

I would like to invite everyone attending the 2008 ASME IMECE next week in Boston to attend a keynote lecture given by Prof. Ted Belytschko of Northwestern University.  The lecture will occur at 1:45 PM on Tuesday, November 4, and will be entitled "Multiscale Computations of Fracture - When Does Flaw Tolerance Occur?" 

Further information on Prof. Belytschko's talk can be found here:

 It is a common technique in modelling cracked bodies with finite element method, to refine the mesh near the crack tip. It is mentioned in text books, mesh refinement is nessecary to increase the acuuracy of the computed stress intensity factor for the crack tip. Is meshrefinement nessecary for computing eigen-properties ( natural frequencies and natural modes ) as well as SIF? or eigen properties are not affected much by the near crack tip field?
