Research assistant and PhD position at PoliMi on corrosion-fatigue
Raiway axle failures have been the starting point for the studies on fatigue. However, recent accidents and papers (see [1] by Hoddinott) have shown that corrosion-fatigue plays a significant role.
At PoliMi we have recently investigated this topic finding interesting results by corrosion-fatigue tests on small-scale specimens and, recently, a validation of the model by full-scale corrosion-fatigue tests (see papers [2-3]).
INTERNATIONAL CONFERENCE ON EMERGING TRENDS IN MECHANICAL ENGINEERING (1CETME 2010)
I welcome and encourage all my fellow imechanicians to participate in the international conference being organised at Thapar university patiala, punjab, india during november 2010.
The details regarding the conference and research paper format are attached.

PhD student or Postdoc position in Multiscale Modelling
The
Interdisciplinary Centre for Advanced Materials Simulation (ICAMS) is
a new research centre at the Ruhr-University Bochum, Germany. At
ICAMS an interdisciplinary team of scientists from engineering,
materials science, chemistry, physics and mathematics is working on
the development and application of a new generation of simulation
tools for multi-scale materials modelling.
Experimental data showing effect of stress state
While there is a lot of experimental literature available on the effects of stress-state on ductile failure under monotonic loading, corresponding studies on fatigue mostly involves bending and torsion type of combination loading. Unfortunately, such a loading corresponds to one of the principal stresses being negative and therefore not as critical. We could find only two references which show clear effect of biaxial state of stress in a pressurised cylinder subject to additional axial load (Biaxial-tension fatigue of inconel 718, it is a report in UIUC 1989).
Surface Roughness Modelling
My research objective is to import surface roughness (topography) data obtained from metrology instrument (in txt form) and to build a finite element model from this. can anyone has same experience as that of mine n can help me in this regard. do someone has matlab m-file to do this and can send me???
thanks in advance
Subsea Integrity
I am teaching Subsea Integrity for the MSc students majoring in Subsea Engineering at the School of Engineering, University of Aberdeen. This is a course that combines the fundamental principles (corrosion, fracture, fatigue and material selection) with the industry applications (subsea integrity management and implementation, cathodic protection, case studies on subsea reliability and engineering assurance).
Teaching time schedule
New idea in fatigue problems
there are two analytical concepts that are very important in fatigue failure.the first one is crack closure and the others is residual stress .the first one is in behind of crack and the other emphasis in the front of crack tip. the question is if we use some devices such as AFM/SEM is it possible we model the energy filed during fatigue process? if this idea can be investigated the second question can be asked: is there any similarity to model for different loading conditions?
I appreciate if you also put your comment in my idea?
