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 http://www.val-conf.org.

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 (www.lboro.ac.uk/moam) 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
assumption"
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.


Overhead Electrical Conductors

Mechanics of overhead electrical conductors under wind excitation is a complex problem . It is described in detail in  the following book:

HOW TO APPLY CYCLIC LOADS IN ABAQUS

I've performed a experiment in fatigue.I need to now perform analysis in ABAQUS and validate the results.

MY QUESTION IS - HOW TO APPLY CYCLIC LOADINGS IN ABAQUS,SAY FOR INSTANCE I'VE RUN 60000 CYCLES AT 10 HZ AT A MAXIMUM-MINIMUM LOAD OF 18 KN - 2KN

Research engineer position at Cenaero as software developer in fracture mechanics, Belgium

The position concerns contribution to the development of Morfeo, a manufacturing oriented finite element software. For any of the project activities, the candidate is expected to develop the numerical methodology up to industrial maturity. First of all, the candidate will contribute to the fracture analysis module of Morfeo. Morfeo relies on an innovative approach based on the extended fi nite element method (X-FEM) in order to easily handle complex industrial applications. Developments include general modeling of the crack propagation and the damage tolerant approach, contact, multi-crack analysis and parallel implementation of the algorithms. Targeted applications include e.g. determination of crack propagation paths on industrial large-scale components and fatigue analysis.

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.

The paper has been published in Scripta Materialia and can be downloaded from:
