This is the second announcement about the upcoming Workshop on Computational Fatigue Analysis 2017, this year dedicated to Design and Fatigue of Weldments (WCFA2017-DFW - http://www.pragtic.com/DFW.php). The workshop is held in Prague, Czech Republic in November 13-16, 2017. The key lecturer, who guides the audience through various issues of the fatigue analysis in welds, is Dr Zuheir Barsoum from KTH - Royal Institute of Technology in Sweden.
Being able to accurately predict the life span of physical bodies, both living and non-living, has been one of humankind’s eternal endeavors. Over the last 150 years, many attempts were made to unify the field of Newtonian mechanics and thermodynamics, in order to create a generalized and consistent theory of evolution of life-span.
My friend and former colleague, Dr. Louis Cloutier, passed away on February 26. A long time Hydro-Quebec engineer, among other achievements, he will be remembered for his major contribution to the solution of electric power transmission mechanical problems, most notably to Aeolian vibration control, and related conductor fatigue.
We provide a very simple result for a problem which has been often neglected (variable amplitude loading) in academia, but which is of paramount importance in real engineering situations, where fatigue is almost never "constant amplitude".
We found few cases where we could check this extremely simple result, but it worked very well. We would welcome further verifications.
The paper is in press here.
One PhD (4 years) and two Postdoc (3 years) vacancies are available in the composites research group at Ghent University in Belgium. The different open positions deal with nondestructive testing methods for composites inspection (vibration/thermography) and fatigue of 3D printed metals.

I am actually using Abaqus' Contour Integral for the determination of stress intensity factors. But I do not know, which theory it is based on. Is it the same like the path-independent determination of J integral? Or is there a difference?
