Reminder - abstract submission date for 3rd IC Engineering Failure Analysis

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.    

I hope you can take the opportunity to network in Sitges with people of similar research interests at this informative and well-received single-stream conference. 

Best wishes

Reminder - abstract submission date for 7th IC Fatigue Damage of Structural Materials

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.

Multi-Axial Failure Models for Fiber-Reinforced Composites

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.

review on KLJ's most loved areas in contact mechanics

Choose a channel featured in the header of iMechanica: 

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!

Regards, Mike

Nitinol, stent fracture and related issues

Choose a channel featured in the header of iMechanica: 

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:

The 13th International Conference on Experimental Mechanics

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.
