The Bundesanstalt für Materialforschung und -prüfung (BAM) is a materials research organization in Germany. Our mission is to ensure safety in technology and chemistry. We perform research and testing in materials science, materials engineering and chemistry to improve the safety of products and processes. At BAM we do research that matters. Our work covers a broad array of topics in the focus areas of energy, infrastructure, environment, materials, and analytical sciences.

The aim of the project „Combining physics- and data-based models for 3D concrete printing – process optimization and safety assessment“ is to develop a digital twin for extrusion-based 3D printing. For that, a numerical model of printed concrete covering the time dependent material behavior (hydration, thixotropy, plasticity, ...) will be derived and implemented in the OpenSource Software FEniCS. The virtual model will be calibrated and verified in automatic and reproducible manner by measurement data. Joining the virtual model with the real process will lead to a framework for optimization regarding the design's safety and robustness. The project is cooperation between division 7.7 “Modelling and Simulation”, 7.4 “Technology of Construction Materials” and S.3 “eScience” of BAM as well as the TU Eindhoven, where the PhD takes place.

We are looking for talented people to join us.

Your responsibilities include:
  • Implementation of an elasto-plastic material model (e.g. Mohr-Coulomb) with time dependent material parameters simulating the structural build-up of printing concrete
  • Linking the model with a hydration model
  • Developing and coordination of a measurement data basis for material characterization
  • Model calibration and validation including uncertainties
  • Developing and implementation of the interface between numerical model and real printing process as well as stochastic process optimization
  • Presentation and publication of the results in research journals as well as on national and international conferences
  • Interdisciplinary cooperation and transfer with national and international research groups
  • Your qualifications:
  • Good university degree (diploma/master) in engineering or similar
  • Very good experiences in technical mechanics and finite element method in the context of structural mechanics
  • Experience in the implementation of FE-software (e.g. implementation of material routines, time integration methods or element formulations)
  • Programming skills , especially with python
  • Interest in developing data basis for structuring and storing of measurement data and model parameter estimation
  • Good written and spoken English skills (German skills welcome)
  • Goal-oriented and structured way of working, initiative/commitment, and ability to work in a team/willingness to cooperate as well as presentations and publication ability
  • Good communication and information behavior
  • We offer:
  • Interdisciplinary research at the interface of politics, economics and society
  • Work in national and international networks with universities, research institutes and industrial companies
  • Outstanding facilities and infrastructure
  • Flexible working hours and mobile working
  • Your application:

    We welcome applications via the online application form by 25/11/2022. Alternatively, you can also send your application by post, quoting the reference number 333/22-7.7 to:

    Ms Robens-Radermacher will be glad to answer any specific questions you may have. Please get in touch via the telephone number +49 30 8104-4789 and/or by email to annika.robens-radermacher@bam.de.

    BAM pursues the goal of professional equality between women and men. We therefore particularly welcome applications from women. In addition, BAM supports the integration of severely disabled persons and therefore especially welcomes their applications. With regard to the fulfilment of the job advertisement requirements, the application documents are examined individually. Recognised severely disabled persons will be given preferential consideration if they are equally suitable.

    The advertised position requires a low level of physical aptitude.
