Generation of Volume Elements for Fiber-Reinforced Polymers via Multi-Body Simulation
Job Description
Req ID:  1249
Place of work:  Braunschweig
Starting date:  12.05.2025
Career level:  Student research project and final thesis
Type of employment:  Part time, Full-time
Duration of contract:  As agreed upon and according to the study regulations, a minimum of 6 months should be planned.

Remuneration: Remuneration is in accordance with the Collective Agreement for the Public Sector - Federal Government (TVöD-Bund)

Enter the fascinating world of the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt e. V.; DLR) and help shape the future through research and innovation! We offer an exciting and inspiring working environment driven by the expertise and curiosity of our 11,000 employees from 100 nations and our unique infrastructure. Together, we develop sustainable technologies and thus contribute to finding solutions to global challenges. Would you like to join us in addressing this major future challenge? Then this is your place!

Would you like to become part of our innovation-driven research team and help shape the future of lightweight system? We, the Institute of Lightweight Systems, develop and test new lightweight construction technologies for resource-saving and climate-friendly structures in the aerospace, transport, energy and security sectors. Our vision is intelligent lightweight system construction for an emission-free tomorrow.

What to expect:
We work as a team on the development of new methods for generating representative volume elements (RVEs) for fiber-reinforced plastics (FRPs) to represent the material's microstructure as realistically as possible. Conventional methods often reach their limits with high fiber volume fractions and complex fiber geometries. Innovative algorithms are being developed to enable more efficient and accurate creation of RVEs. An interesting approach in this regard is the use of multi-body simulations to realistically model the fiber arrangement in the matrix.

 

Your tasks:
As part of the student research project, a novel methodology for generating RVEs based on a multi-body simulation is being developed and implemented. The interactions between the fibers are simulated to achieve a realistic representation of the microstructure, where the fiber volume fraction does not play a significant role. Additionally, various spatial descriptors are integrated to assess the generated topology in terms of relevant geometric and statistical properties.

 

Your profile:

  • ongoing studies in Mechanical Engineering, Materials Science, Aerospace Engineering, or a related engineering field
  • interest in numerical simulation and material modelling of composites
  • basic knowledge of multi-body simulations or willingness to learn about the topic
  • programming skills in Python
  • enhanced Problem-Solving Skills

We offer

DLR stands for diversity, appreciation and equality for all people. We promote independent work and the individual development of our employees both personally and professionally. To this end, we offer numerous training and development opportunities. Equal opportunities are of particular importance to us, which is why we want to increase the proportion of women in science and management in particular. Applicants with severe disabilities will be given preference if they are qualified.

We look forward to getting to know you!
