Converted into post-doctoral position (and filled) : Open PhD position: Optimization of Addendum Surfaces In Stamping at UTC

Submitted by breit on

We are currently seeking a PhD student to pursue research project within the Roberval Laboratory at Université de Technologie de Compiègne, France. The position is available in the scope of the OASIS project "Optimization of Addendum Surfaces In Stamping" involving several French academia and industrial partners.

The overall goal of the project is to propose methodologies to optimize the process parameters for service properties of high elastic steel parts, while taking into account the residual stresses due to the stamping process. 

Literature regarding the appearence of cracks in steel. Thermal, pressure fatigue

Submitted by danielel on

Hello!

I am wondering if anyone could recomend som literature for me to get my hands on.

If there is any literature regarding how the appereance of a crack in a piece of thin metal (~0,5mm - 1 mm) could be related to pressure fatigue or thermal fatigue.

Does the crack due to thermal fatigue have a specific appereance and so on. I need get my hands on practical pictures and so on, not equations.

Are there any signs in the vicinity of the crack that is indicating that this could be due to pressure fatigue.

Any help is much appreciated.
