hi all,

I am facing problem in understanding stress intensity factor. How exactly i can analyse crack propagation through SIF. In books it is given that SIF characterises the crack. But in numbers how can i know whether this crack will propagate for this value of SIF. According to westergaard equation crack tip stresses will go to infinity if θ and r tends to zero for any value of crack length. Please somebody help regarding this. If iam technically wrong please correct me.

Thank you

Hi

Congratulations to Julian Rimoli (who's one of the moderators of iMechanica) for winning the 2010 James Clerk Maxwell Young Writers Prize!

The School of Civil and Environmental Engineering invites applications for two tenure-track faculty positions in structural engineering/mechanics/materials (SEMM). Candidates at all ranks are sought with expertise in one or more of the following areas: (1) computational/solid mechanics; (2) infrastructure materials. The expected starting date is August, 2011.

18th International conference on Wear of Materials

To register go to http://www.wom-conference.elsevier.com/registrationInfo.asp

Please check out the oral program for WOM 2011 at www.wom-conference.elsevier.com

The Centre for Research in Computational and Applied Mechanics (Cerecam) at the University of Cape Town, South Africa, invites applications for a post-doctoral fellowship in nonlinear computational mechanics. Further information about the position may be obtained from Professor
Daya Reddy (daya.reddy [at] uct.ac.za).

A post-doctoral position is available in the Dept. of Chemical Engineering at the
University of Pittsburgh to conduct experimental research on developing
"morphing surfaces" that change topology by developing features such
as bumps, folds, spikes, etc. The post-doctoral fellow will develop (1)
surfaces that undergo a change in topology in response to applied stimuli, (2)
methods to control the shape and location of the morphing features on the
surface, and (3) quantitative or heuristic models to guide the design of
texture-changing surfaces.
