Postdoctoral Researcher (m/f/x)

ICAMS: Micromechanical and Macroscopic Modelling

In order to fill a fixed-term position in full-time (39.83 hours/week = 100%) at the earliest possible date, we are looking for a

The Interdisciplinary Centre for Advanced Materials Simulation (ICAMS) is a research centre at the Ruhr-Universität Bochum, focusing on the development and application of multi-scale simulation tools for advanced materials. ICAMS is embedded into a network of national and international collaborations. Researchers and students benefit from this top international and interdisciplinary environment. The department Micromechanical and Macroscopic Modeling is actively doing research on process-microstructure-property relationships for metallic materials under various conditions. The focus of our work lies on scale-bridging modeling in close collaboration with experimental partners.

The tasks associated with the position include implementing a process model for Friction Stir Welding (FSW) based on physical principles and applying the model to predict microstructures resulting from FSW process by considering the complex interaction of thermo-mechanical loads and severe plastic deformation. The model predictions are validated against experimental results. The position offers substantial freedoms to implement creative, pragmatic solutions in a supportive environment.

• Scope: full-time
• Duration: fixed-term,16 months (project duration)
• Start: at the earliest possible date
• Apply by: 2026-10-13

Your tasks:

• Implementation of a micromechanical process model based on the Smoothed Particle Hydrodynamics (SPH) method and crystal plasticity.
• Formulation of a macroscopic mean field process model describing the microstructure evolution during the FSW process based on statistical descriptors obtained from the micromechanical model.
• Validation of predicted microstructures and residual stresses based on experimental data from collaboration partners.

Your profile:

• Outstanding, science-driven candidate with a strong background in mechanics of materials and a Ph.D. in Materials Science, Computational Engineering, or Physics
• Expertise and experience with numerical methods in solid mechanics, including large plastic deformations, ideally with crystal plasticity
• Fundamental understanding of materials physics and mechanisms of microstructure evolution under thermo-mechanical loads
• Willingness to collaborate in a team with other modeling and experimental research groups
• Demonstrated programming experience in Fortran and Python

We offer:

• Team-oriented cooperation in a committed, international, and appreciative team
• Options for flexible working hours
• Extensive training and further education opportunities
• A job in the lively Ruhr metropolitan region with its diverse cultural offerings
• A friendly and collegial environment

Further information:

The position is salaried and based on the collective agreement of the Länder (TV-L).If the personal and collective agreement requirements are met, the employee will receive pay grade E13 TV-L.
