Postdoctoral position in Self-consistent crystal plasticity modelling

You are invited to apply for a post-doc position in self-consistent modelling for neutron scattering applications. The position is placed at the Department of Industrial and Materials Science (Division of Material and Computational Mechanics), Chalmers University of Technology, in Gothenburg, Sweden (www.chalmers.se).



The development and improvement of experimental methods to study the micro-scale mechanics of materials in-situ have in recent years opened up new possibilities for generating more detailed knowledge and understanding of the underlying physical processes. Instruments at the European Spallation Source (ESS) will offer unique possibilities for in-situ analysis of stresses, strains, and phase behavior in engineering materials (such as metals or ceramics) during service and/or process-like conditions. Detailed analysis of the data resulting from such experiments is, however, complicated and requires advanced modelling and simulation tools.



Project description
In this project we will develop such tools and make them publicly available through web applications. Specifically, numerical efficient self-consistent algorithms for analysis of internal stresses, strains and texture will be utilized and developed. The resulting analysis software will be offered as a web service utilizing an established web framework in conjunction with cloud computing. Thereby neutron diffraction experiments will be made accessible to actors (industrial or academic) with limited experience and/or without resources for advanced analysis. The project will be performed in collaboration with the Data Management and Software Centre at ESS (Copenhagen) in order to integrate the services into existing infrastructure.



Research environment
Research areas the Division of Material and Computational Mechanics comprise the mechanical modeling of materials, components, structures and processes. The research is interdisciplinary in the following areas: Lightweight materials and structures, Multi-phase materials, Process modelling and simulation, Railway mechanics and Structural mechanics. The current post-doc position will be placed at this division but the work will be done in strong collaboration with the Division of Materials Microstructure at the Department of Physics.



The research in the Division of Materials Microstructure is focused on understanding the relation between microstructure and properties of materials, and how the microstructure evolves during processing and operation. The goal is to provide knowledge that can be used to develop new materials and to optimize composition, production routes, heat treatment etc.  This is mainly achieved by applying advanced characterization tools such as electron microscopy, atom probe tomography and neutron and synchrotron X-ray scattering and diffraction.



Major responsibilities
Self-consistent modelling based on crystal plasticity is commonly used to analyze the detailed response of polycrystals to externally imposed deformation during neutron scattering experiments. The aim of the proposed post-doc project is to develop and implement a state-of-the-art self-consistent framework capable of handling the specific conditions occurring during high-temperature and thermo-mechanical deformation conditions, which will accessible at future ESS beamlines. The resulting software will be made available as a web service (SaaS = software-as-a-service) using an established web framework and utilizing cloud computing resources.



The position also includes teaching on undergraduate and master's levels as well as supervising master's and/or PhD students to a certain extent. Another important aspect involves collaboration within academia and with society at large. The position is meritorious for future research duties within academia as well as industry/the public sector.



Position summary
Full-time temporary employment. The position is limited to a maximum of two years (1+1).



Qualifications
You should have a strong background in computational mechanics with a PhD degree from an internationally recognized university. The degree should generally not be older than three years. Knowledge and research experience in continuum mechanics, material mechanics and multi-scale modeling of materials are absolutely essential. Experience in crystal plasticity and/or self-consistent models is a significant advantage. Furthermore, experience in code development is a pre-requisite, prior exposure to software development and engineering will be considered an advantage. Since you will work together with researchers in Physics, insight into materials science and in particular neutron diffraction experiments is also meritorious. You are expected to be able to work both independently and in a team and to have good communication skills.



The position requires sound verbal and written communication skills in English. 



Information about the department
The main competencies at the Department of Industrial and Materials Science are found in the areas of: Human-Technology Interaction | Form and Function | Modeling and Simulation | Product Development | Material | Production and in the interaction between these areas. The research develops the industrial process, from need to finished product while creating added value. To combine skills throughout the whole chain distinguishes the department both nationally and internationally. Here we gather internationally prominent researchers, in dynamic and outstanding research environments, as well as in national and international research networks.
