Given the complexity of present and
future global challenges, it is the university´s social responsibility
to contribute to society by understanding the full extent of its needs
and current and future problems, and to prepare it to deal with them
effectively and efficiently (CMES, 2009)1. In this sense, due to its
ability to take the lead in matters of knowledge creation, promotion and
dissemination, the university becomes the ultimate guidance governments
possess in their quest to find solutions to inequality and exclusion.

Wear-out models for composite materials fatigue, and the "strange case" of Kassapoglou's "too good to be true" model

Wear-out models have been very successful for fitting probabilistic SN
curves of composite materials.  The "strength-life equal rank
wear-out models for fatigue of composite materials were
first presented by Hahn and Kim [1], and later as a fitting approach to fatigue
data by Sendeckyj [2].

sad news for mechanician. Departure of HD Bui, member of french academy of science

Unfortunately, HD Bui, 76, passed away yesterday evening. An elegant, dedicated, very discreet but bright mind, HD Bui made a long career at Ecole Polytechnique and EDF, making important contributions in fracture mechanics and inverse engineering.  Lately, he returned to work on his interesting contributions on the Cheops pyramid and the spiralling internal structure.

He was considered the most prominent vietnamese scientist in France, of 400 000 living there.

retirement age or discrimination? Nature speaks of "sticking" around, but in europe we have new laws

In January 2011, the UK government announced its intention to stop
compulsory retirement for people aged 65, despite criticism of the move
by employers’ groups. Campaigners against age discrimination and unions
welcomed the change. However, official guidance makes it clear that
employers will be able to dimiss staff no longer capable of carrying out
their work. Official figures show more than two thirds of British
employers have already eliminated fixed retirement ages.

Mechanics of love and happiness

An interesting application of non linear dynamics, including happiness with a simple 1D damped oscillator!

A simple approximate expression for finite life fatigue behaviour in the presence of ‘crack-like’ or ‘blunt’ notches

After a long process (somebody may recall I made also quite some chaos on imechanica to complain with the review process in a previous journal), this paper was accepted.  Ask me a preprint if you are interested.  I can attach here a few images only.

Politecnico di Bari, 70125 Bari, Italy
Received in final form 13 June 2011

Benoit Mandelbrot dies at 85

Mandelbrot has passed away last week.  A very interesting  mathematician, who received tenure from Yale only at 75, he has introduced fractals also in fracture mechanics.

Neet generation, generation not-not, generacion ni-ni, many terms one meaning!


I think I have spoken various times of this problem.

In Italy there was today an announcement that we have the biggest such problem in Europe.  See here .

When I search in wikipedia, I find various terms.

NEET in Uk, Japan, China, South Korea

Some example videos of my new YouTube channel course "Mechanics of Materials" (italian)

Given the success of my facebook course Mechanics of Materials MMCM see here, we had so many videos and photos, that I suggested the students to create a Youtube channel.   Here it is, with many videos based on powerpoint presentations I had from my course, and that of collegues in Torino (Masssimo Rossetto), or some conferences presentations, which the students transformed into videos.  Thanks in particular to Mariella Greco, and Simone Legari.

The shape of the Eiffel Tower

I've got interested, since I am going with about 10 of my students to Paris for the Euromech conference I am coorganizing in July, by the design of the Eiffel Tower.  Eiffel was a great engineer, and indeed his shape of the tower apparently comes from his ingenious idea of  balancing weigth and wind pressure so that there is little need of foundations.  WIKIPEDIA has an account of this design idea, and the resulting integro-differential equation.

Is Your Thesis Hot? Or Not? --- check it out !

Is Your Thesis Hot? Or Not?

Writing a thesis about animal intentionality and tool use is
totally hot right now. A thesis about Robert Louis Stevenson's use of
the supernatural to symbolize evil? Not so much.

statistics about students in world universities

dear Friend

I am comparing italian universities with Russian ones with US and with Cuban ones. Then I need some figures.

I have been able for example to find that there are about 50% of students-workers in Russia, what about US?
I mean full time workers, not just part time.

Promotion at random is better! Tenure makes you more "incompetent" -- Peter's principle proved by two italian scientists!

If you are upset about promotion system, look at what two italian friends proved recently, which was immediately popular before the paper publication, also because they proved random promotion is more efficient!
