XVIII International Colloquium on Mechanical Fatigue of Metals (ICMFM XVIII) - First announcement

Dear Colleagues,

It is our great pleasure to announce the XVIII International Colloquium on Mechanical Fatigue of Metals (ICMFM XVIII), which will take place at the Universidad Laboral in Gijón (Spain), the 5th, 6th and 7th of September of 2016. The event will be organized by the Engineering School of the University of Oviedo.

PhD position on multi-scale modelling of fatigue damage in composites @ Ghent University (Belgium)

The core idea of this project is to develop a consistent multi-scale modelling framework for fatigue damage in unidirectionally reinforced composites. Three scales are distinguished:

Course on Design Principles, Fatigue & Damage Tolerance for Aeronautical Engineers

Dear iMechanicians,

Please note that a 6 day course for aeronautical engineers on design principles, fatigue and damage tolerance will be realized during October and November 2014 in Czech Republic. The course is split to two blocks: Part I - Design Principles; Part II - Fatigue & Damage Tolerance run in the period October 20-22 and November 11-13 respectively.

1st invitation to VAL 2015 conference discussing effects of variable amplitude loading

Dear iMechanicians,

Let me invite you the 3rd International Conference on Material and Component Performance under Variable Amplitude Loading (VAL 2015) taking place in Prague, Czech Republic in March 23-26, 2015. See the details on its website

The conference will discuss among others these primary questions:

Project Associate / PhD Positions: Multiscale Simulation of Nano-Composites for Fatigue & Fracture

Applications are invited for few open positions in the area of
multiscale simulation of fatigue and fracture of advanced alloys and
nano-material based composites. Primary focus of this research is investigation
of fatigue and fracture behavior of nanomaterials and to develope various
constitutive models for continuum, based on large scale atomistic simulations.
Research effort will include development of analysis and design methods toward
improving material/structural behaviour using computer simulation. Interested
candidates should have preferably MTech/ME degree in
mechanical/civil/aerospace/material engineering discipline with good knowledge

Research Associate - Modelling of Crack Growth under Fatigue-Oxidation Conditions

A Research Associate is required to undertake an EPSRC-funded project to model oxidation damage at a crack tip and associated crack growth for nickel alloys.

You will join the vibrant Mechanics of Advanced Materials group at Loughborough ( which has gained significant experience in the study of mechanical behaviour of advanced materials.

the relationship between the elastic constant of the metal and the the number of the fatigue cycles?

Is there a relationship between the elastic constant of the metal and the the number of the fatigue cycles?If we can find the relationship of the stand test spesimen,can we use that  relationship to predict the fatigue life of other structures?

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].

Size Effect in Fatigue of Metals

Hi everyone,

So it has been a while now that I am trying to understand the concept of size effect seen in fatigue of metals.

As far as I have understood(if correctly!), size effect in metals is more due to a fractal nature, rather than energetical because the fracture process zone is small in metals. I have seen also papers which use fractal theories to account for it.

I have seen a good deal of research done by Bazant for concrete and quasi-brittle materials, but somehow I cannot make a proper analogy for metals.

Fatigue of polymer-supported Ag thin films

The fatigue behavior of Ag films on polyethyleneterephthalate substrates was studied using electrical resistance measurements.
Scanning electron microscopy images showed two types of failure: typical fatigue failure with extrusion–intrusion pairs, and ductile
failure with local necking. Once through-thickness cracks are formed in the metal layer, cracks propagate and the resistance increases abruptly for both failure modes. The effect of adhesion on fatigue life is discussed in terms of concurrent delamination, crack initiation and propagation.
