Apply online Are you interested in contributing to development of metallic components for wind energy? If so, the department of Wind Energy, Division of Materials and Components invites applicants for a postdoc position in the area of multi-physics weld modeling of large-scale cast iron components for wind turbines. Responsibilities and qualifications The research position is part of a project funded by the Innovation Fund Denmark, which seeks to develop a game-changing welding technology that will enable assembly welding and repair welding of large-scale cast iron components for wind turbines. The successful applicant will be a member of a larger team of university researchers working closely together with the major companies in this project, which include welding institutes, foundries, and wind turbine manufacturers. The postdoc project aims at advancing the state of the art in the area of multi-physics modelling of welding processes of large-scale cast iron components. The main objective of the project is to develop a thermo-mechanical model to predict residual stresses (RS) induced by different welding processes, and use the RS data and 3D X-ray tomography data of the weldment in a fatigue model to predict the lifetime of the large-scale cast iron weldments. Your primary responsibilities and tasks will be to: Develop a thermo-mechanical model for predicting residual stresses (RS) induced by various welding processes for different welding parameters and heating/cooling conditions and optimize the process parameters. Develop fatigue model for cast iron using experimental 3D X-ray tomography data input Integrate RS model with fatigue model to predict the lifetime of welded large-scale cast iron components Disseminate the results in peer-reviewed journals As a formal qualification, you must hold a PhD degree (or equivalent). Furthermore, strong English communication skills are essential. Applicants should be highly motivated, ambitious, and eager to seek and share knowledge, willing and able to work as part of a team as well as through interdisciplinary collaboration with industrial partners and across the sections in DTU Wind Energy department. More specifically, you should have the following qualifications: Experience in thermo-mechanical modeling of welding processes Strong knowledge of Finite-element modeling and multi-physics modeling Good knowledge of fracture mechanics and fatigue of welded components Experience in finite element softwares such as Abaqus and Ansys as well as programming skills in Matlab, Python, and Fortran is a plus.
