**C**-TEC RECRUTE**

**INTERNSHIP - R&D ENGINEER F/H/X**

**PROJECT TITLE : « Edge cracking test evaluation »**

Edge cracking is a failure mechanism occurring during stamping of autobody panels. It is strongly affected by the shearing process used for preparing blanks prior to forming. During stamping, the metal flow into the die induces deformation of the blank edges. When the edge is stretched in tension, failure may occur due to lack of ductility and/or poor quality of the blank preparation. The project objective is to implement a laboratory test measuring the resistance to edge cracking. Experimental work will be carried out on various aluminium alloys for their classification. Metallurgical analysis will also be performed to identify the elements impacting sensitivity to edge cracking.

The project has several components:

- Literature review of existing edge cracking tests and experimental procedures.
- Mechanical testing instrumented by Digital Image Correlation.
- Identification of relevant indicators to quantify strain localization.
- Evaluation of aluminium alloys performance, especially of recycled versus standard alloys.
- Analysis and synthesis of the results, report writing and presentation to the team.

At C-TEC, the intern will be part of a R&D team of engineers with expertise in metallurgy and mechanics.

**Education level : Engineering school or Master of Science**

**Competencies & technical & soft skills requirement**:

- Good knowledge in mechanics and physical metallurgy
- Motivation for both modeling and experimental work
- Strong capacity to post-treat a significant amount of data from both simulations and experiments
- Serious, autonomy, critical mind and creativity
- Good English level, both written and spoken
