A new section on applications has been added to the website on failure criteria. Six examples of failure applications are given which span the range from very ductile to very brittle isotropic and homogeneous materials. Summarizing two of the examples, first a very ductile polymer is examined wherein its tensile, compressive, and shear strengths are determined as influenced by a state of superimposed hydrostatic pressure. An interesting fallout from the example shows just how seriously in error the Mises criterion can be, even when applied to a ductile material.
Submissions are now closed for oral presentations to WOM 2011, however, contributions are invited for stand-alone posters. WOM 2011 is to take place in Philadelphia, USA - April 3-7 next year. It will focus on both the fundamental and applied aspects of wear and friction of materials at the macro-, micro- and nano-scale. Special emphasis will be placed on wear issues in harsh environments, energy conversion, and debris particle generation and its impact on the environment.
Hi
I am modelling the crack propagation in metals. I can do all the modelling but only adding the enrichment function in ABAQUS is an issue. I have defined the initial crack(for the CT speciemn), which starts at the node, but when I submitt the job it does not separate at that node. I think it because I did not define the enrichment functions.
I would like to know how to add enrichment function in abaqus when modelling the crack propagation. Any suggestion would be appreciated.
Thanks in advance

Dear Friends,
I have to give a seminar on any topic in cad/cam/cae. But i can't find a good one yet.Please someone suggest me a good topic if you have any idea about it. That will be really helpfull.
Hi I'm looking for a Johnson Cook damage criterion for Alloy 718 (or Iconel 718) i.e. the constants (D1,D2,D3,D4,D5).
If anyone seen an article or book with these constants I would be thankful if you could help me out.
Thanks in advance
A postdoctoral position is available starting immediately in the Johnson Research Group at the University of Illinois at Urbana-Champaign. The position will involve theoretical and computational modeling of the mechanics of soft materials/flexible electronics/adhesion, with applications in photonics and energy storage. The work will involve significant interactions with experimental groups in the Department of Materials Science at the University of Illinois. Applicants should send a CV with a list of references to htj [at]
i am analyzing of fgm cylindrical shell that chang property in the thickness.
i want use abaqus subrotine or other sutable sofware.
can you help me?
