The full oral program for the 7th International Conference on Fatigue Damage of Structural Materials is now available at http://www.fatiguedamage.elsevier.com/index.htm. Join your peers by registering for this popular single-stream meeting held in Hyannis, MA, USA on beautiful Cape Cod, September 14-19, 2008.  

The abstract submission deadline for this next conference in the biennial Engineering Failure Analysis series (www.icefa.elsevier.com) is 30 November 2007.

The conference will take place in the coastal town of Sitges, just a short distance from Barcelona's international airport, from 13 to 16 July 2008.    

The abstract submission deadline for this next conference in the biennial Fatigue Damage of Structural Materials series (www.fatiguedamage.elsevier.com) is 28 November 2007.

The conference will take place will take place in Hyannis, MA, USA, 14-19 September 2008. Hyannis is located on the beautiful Cape Cod peninsula just 90 minutes from Boston's Logan International Airport and T.F.Green Airport in Providence.   

The increasing use of fiber-reinforced composites accentuates the need for developing multi-axial fatigue failure models for these materials. In this article (attached), we proposed several multiaxial fatigue failure models for fiber-reinforced composites considering the contribution of mean and cyclic normal stress/strain and shear stress/strain at the plane of failure and examined their capability for predicting the fatigue life of the E-glass/epoxy composite materials.

If we read Ken Johnson’s Timoshenko medal 2006 speech also posted in iMechanica, the subjects Ken mentions in his brief and humorous speech are:-

1. corrugation of railway rails,
2. the damping at clamped joints,
3. Hertz contact under the action of tangential friction forces,
4. ‘tribology' (word invented by David Tabor along with F.P.Bowden in Cambridge),
5. Atomic Force Microscope, Surface Force Apparatus & friction on the atomic scale,
6. Relation between adhesion and friction.

These are probably the subjects Ken is most attached to. Some are older (but perhaps not solved, lke corrugation, for which the “short-pitch” fixed wavelength mechanism is still unclear despite Ken’s 40 years of efforts (!), and some are certainly fashionable today (like adhesion and friction at atomic scale). In starting this forum, why not start from here? Should we prepare a 1 page summary on each of these topics? Since I start this, I will do the effort on corrugation I promise in the next week or so!

Stent and Nitinol have revolutionized the medicine.  In past decades, guidewires, stents, filters and many minimumly invasive devices and implants are made of Nitinol and they proved to be very successful.

However, the fatigue behavior of Nitinol has not been well understood.  As a consequences, many stent fractures have been observed in-vivo.  Below is a list of misconcepts that may contribute to the widely observed in-vivo fractures on Nitinol stents:

Dear Colleagues:

The 13th International Conference on Experimental Mechanics (ICEM13, http://www.icem13.gr) will be held on July 1-6, 2007 in Alexandroupolis, Greece. It is our pleasure to announce that the Conference will include a special symposium organized by us entitled, “Plasticity, Fracture and Fatigue at the Micro and Nano Scales,” which will focus on recent developments in this area within the larger scope of assessing research needs in a variety of applications of interest.

I would like to invite you to participate in the referenced symposium and to present a paper. If you decide to participate, please submit an abstract on-line through the ICEM13 web site http://www.icem13.gr no later than *October 31, 2006*. The deadline for submission of /manuscripts/ will be announced at a later time. The presented papers will be included in the Proceedings of ICEM13 published by Springer.

Horacio Espinosa and Emmanuel Gdoutos
