Current work
Currently I am working on SW tests and test automatisation for electronic systems in the automotive field:
- test concepts and systematic test case creation
- planinng of efficient tests
- tests environment in lab and on the street
- test documentation and defect managent
- regression tests
- software unit tests
Activities as post doc
The inner wall of the fusion reactor ITER will comprise several hundred thousand beryllium tiles. These tiles are hot isostatic pressed and attached to the underlying copper cooling structure. This bond is exposed to thermal fatigue.
To verify a sufficient resistance of the bond for the whole reactor lifetime, several prototypes were tested in a vacuum chamber with a 200 kW electron beam gun at heat fluxes up to 2.5 MW/m². This corresponds to the 1800 manifold sun light intensity.
My task was the coordination with the customer, test planning, execution and reporting of these several month lasting test campaigns. Amongst other thing I pushed the further development of these metallic bonds through FEM simulations and diffusion bonding experiments.
PhD Thesis
Develepment and optimization of functionally graded tungsten/EUROFER97 divertor components - Aim of the project ist the development of production techniques for functionally graded layers out of the structural materials tungsten and EUROFER97
in order to realize a joining between those two materials. The remarkable difference in thermal expansion between tungsten and steel causes a thermal mismatch between them resulting in stresses, which would yield failure of a direct joint. The theoretical assessment of the gain of such functional
graded layers is done by viscoplastic simulations using the finite element code ABAQUS. Vacuum Plasma Spraying, Magnetron Sputtering and Resistance
Sintering under Ultra High Pressure are the most promising fabrication processes, whereas experiments will reveal their suitability.
