Dear Colleague,

We are pleased to announce the10th European Solid Mechanics Conference – ESMC 2018, which will be held in Bologna (Italy) duringJuly 2-6, 2018.
The Conference is organized by the University of Trento and the University of Bologna.

The stress concentration induced by fretting fatigue was studied with a simple "Crack Analogue" model (CA) by the MIT group of Suresh in the late 1990's, which was then "improved" by the present author to take into account simply both contact loads and bulk stresses loads, and even the case of finite stress concentration in the so-called "Crack Like Notch Analogue" (CLNA) model.

Abstract

Jim Barber and I just got accepted this paper in JMPS, and it is also already available on Arxiv. We found a remarkably simple closed form solution for adhesion on orthotropic materials in the planes of symmetry. This shows adhesion can increase significantly due to anisotropy, namely the JKR solution continues to hold in the sense of mean elastic modulus, but the prefactor can grow without limit. We expect applications in crystals indentation, but also in locomotion in biological world.

Would you believe this story?

To me, that metal - on - metal had large friction, especially with the newest designs, it was clear from the old Sir Charnley studies in Leeds in 1950s published in his gold book.

Anyway, when I looked at ceramic on ceramic joints, I also found evidence of increased friction. Maybe ceramic debris is less toxic?

Please comment. What can we do outside USA to improve the situation?

Dear Colleagues and Friends,

We are pleased to invite you to contribute to the1st International IEEE Workshop on Metrology for Aerospace.

The event is co-technical sponsored by two IEEE Societies, AESS and IMS.
The event includes but is not limited to new technology for metrology-assisted production in aerospace industry, aircraft component measurement, sensors and associated signal conditioning for aerospace, calibration methods for electronic test and measurement for aerospace.

Dear Colleague:

I received this letter from Prof Davide Bigoni

Marie Curie PhD position at University of Trento (Italy): deadline September 15

It is a top opportunity in Italy, the leading group in Italy in elasticity, plasticity and nonlinear elasticity. A very active university and town.

I expect many applications.
