Deepdrawing: numerical simulation with ABAQUS, material characterization via Nakajima tests and laboratory experiments During my time at Laboratory for Machine Tools and Production Engineering (WZL) of RWTH Aachen University I was working within the project "Damage-controlled forming processes, influence on damage development during deep drawing". In my role as a Student Research Assistant I was tasked with working on fundamental experiments like Nakajima Test to examine the influence of defined stress states on the damage development of DP800 dual-phase steel. Furthermore, I was working on the development of a finite-element model of deep-drawing in ABAQUS.

Departement Heat Treatment – process optimization of heat treatment furnaces In terms of technology, KAMAX is the world's leading manufacturer of high-strength fasteners for the automotive industry. With locations in the three leading automobile regions of Europe, America and Asia, KAMAX is a key supplier for all major manufacturers and suppliers of the passenger car and commercial vehicles industry. During my work as an intern in the department of Heat Treatment at KAMAX I was tasked with the reduction of scrap- and reworking parts during the annealing process. Due to my review and intensive analysis of the processing data I was able to reduce the quota of reworking parts up to 66%.

Stretch Drawing, Incremental Sheet Forming: laboratory experiments and tooling During my time at Institute of Metal Forming of RWTH Aachen University I was able to gain insights in different variants of metal sheet forming, most significantly Incremental Sheet Forming as well as Stretch Drawing and the process development of said technologies. My tasks included preperation and excecution of laboratory experiments as well as optical forming and deformation analysis with GOM ATOS, ARGUS and ARAMIS. Materials, I worked with include different grades of aluminum alloys, deep drawing/ mild steels and stainless steels.
