Beschreibung

With over 300 employees, the Fraunhofer Institute for Mechanics of Materials
IWMhas been for 50 years one of the leading institutes in Europe for predicting the behaviour of materials using simulations and scientific experiments.

As part of a research group funded by the German Research Foundation (DFG), the influence of local microstructure and process parameters on the formation of adiabatic shear bands (ASB) during high-speed shear cutting (HGSS) is investigated using representative volume elements and the finite element method (CPFEM).

A thermomechanical crystal plasticity material model (ABAQUS UMAT) is used to systematically understand the correlation between ASB formation, process parameters and local microstructure.

What you will do

You will create two and a half dimensional representative volume elements (RVE) for 5000 series aluminum alloys
You will enhance existing crystal plasticity UMAT to include thermal effects (Thermo-Mechanical Coupling)
You would be optimizing the crystal plasticity material model parameters using experimental results
You will conduct a Design of Experiments (DOE) analysis pertaining to ASB initiation.
You will investigate the influence of loading conditions on ASB initiation in RVE

What you bring to the table

You are enrolled and majoring in mechanical engineering, civil engineering, materials science, materials engineering, or a related discipline
You are interested in materials characterization, their structure, and properties
You have good knowledge of engineering mechanics, continuum mechanics, numerical methods, and material modelling
You have previous knowledge in finite element simulation (e.g., ABAQUS), material modelling
You possess basic programming skills (e.g., Python, MATLAB, Mathematica)
You are motivated to do scientific and at the same time industryoriented research
You are able to work independently and have critical thinking skills
You have very good written and spoken German and English skills

What you can expect

Structured orientation: we will maintain your start at the
IWMand give the right support
Flexible working hours to ensure your worklife balance
An open, collegial working environment and a good insight into the division of »Forming Processes«

With its focus on developing key technologies that are vital for the future and enabling the commercial utilization of this work by business and industry, Fraunhofer plays a central role in the innovation process.

As a pioneer and catalyst for ground-breaking developments and scientific excellence, Fraunhofer helps shape society now and in the future.
