This is a premiere: my first contribution to the new ESIS' blog announced in January. Why comment on papers in a scientific journal after they have passed the review process already? Not to question their quality, of course, but animating a vital virtue of science again, namely discussion. The pressure to publish has increased so much that one may doubt whether there is enough time left to read scientific papers. This impression is substantiated by my experience as a referee. Some submitted manuscripts have to be rejected just because they treat a subject, which conclusively has been dealt years before - and the authors just don’t realise.
So much to my and Stefano’s intention and motivation to start this project.

Here is my first “object of preference”:

Ehsan Barati, Younes Alizadeh, Jamshid Aghazadeh Mohandesi, "J-integral evaluation of austenitic-martensitic functionally graded steel in plates weakened by U-notches", Engineering Fracture Mechanics, Vol. 77, Issue 16, 2010, pp. 3341-3358.

The aim of ESIS is not only to develop and
extend knowledge in all aspects of structural integrity, but also to disseminate this knowledge world-wide by means of scientific publications and to educate young engineers and scientists.
For these purposes, three Elsevier journals - Engineering Fracture Mechanics , Engineering Failure Analysis and
International Journal of Fatigue - are published in affiliation with ESIS.

Promoting and intensifying this aim is what we want to achieve through a new blog that ESIS will manage here for discussing some of the papers which appear in Engineering Fracture Mechanics. Its editors, Profs. Karl-Heinz Schwalbe and Tony Ingraffea,fully support this initiative.
