Modeling of microstructure evolution and failure of aluminum under neutron load

Job description

Are you a talented Mechanical Engineering, Computational Mechanics or Applied Mathematics graduate who wants to contribute to the development of sustainable nuclear technologies for medical and energy applications? We are looking for an enthusiastic PhD candidate to work on this exciting and challenging project.

Materials ageing and structural integrity of research reactors Many of the existing nuclear research reactors in Europe are very old (>60 years operation) and only few initiatives are taken to partially replace this capacity. Until new reactors come to operation, continued operation of these existing reactors is required to maintain the EU excellence in development and qualification of nuclear materials for advanced reactor concepts and to maintain the supply of medical isotopes. However, there is limited understanding of damage mechanisms and lack of data on research reactor materials at relevant operating conditions for long term operation of research reactors. In addition, there is a shortage of surveillance specimens for extending the operational life for some research reactors. The EU project Magic-RR addresses these issues and one of its topics is the development of advanced multi-scale modelling methods for prediction of the influence of irradiation on mechanical properties of reactor materials.

Vacancy for a PhD-student

In this project, a framework for modeling of microstructure evolution under neutron loads, and irradiation hardening and embrittlement due to this microstructure evolution under general mechanical loads will be developed. For this purpose, you will

• develop a multi-scale approach that will bridge from the physical processes that occur at the scale of the crystalline lattice and its defects, to mechanical failure at the macroscopic application scale.
• use a combination of modelling techniques, including a cluster dynamics model, crystal plasticity and a probabilistic brittle failure model.
• apply the modelling framework to an aluminum alloy that is used for structural components of research reactors.

Section Mechanics of Materials

You will work in the section of Mechanics of Materials (MoM) at the department of Mechanical Engineering at the Eindhoven University of Technology (TU/e). The research activities of the MoM section concentrate on the fundamental understanding of various macroscopic problems in materials processing, forming and application, which emerge from the physics and the mechanics of the underlying material microstructure. The main challenge is the accurate prediction of mechanical properties of materials with complex microstructures, with a direct focus on industrial and societal needs. The thorough understanding and modelling of processes that can be identified in the complex evolving microstructure is thereby a key issue. The section has a unique research infrastructure, both from an experimental and computational perspective.

Job requirements

• A talented, motivated, enthusiastic candidate with strong analytical skills, initiative, creativity, and flexibility.
• A MSc-degree (with high grades) in Mechanical Engineering, Computational Mechanics, or Applied Mathematics.
• A background and strong interest in mechanics of materials and materials science.
• Experience in multi-scale modelling and micromechanics is of benefit.
• Excellent oral communication and writing skills in English.

Conditions of employment

A challenging job in a dynamic and ambitious university in an interdisciplinary setting and within an international network, with the possibility to present your work at international conferences. You will work on a beautiful, green campus within walking distance of the central train station. In addition, we offer you:

• Full-time employment for four years, with an intermediate evaluation (go/no-go) after nine months. You will spend 10% of your employment on teaching tasks.
• Salary and benefits (such as a pension scheme, paid pregnancy and maternity leave, partially paid parental leave) in accordance with the Collective Labour Agreement for Dutch Universities, scale P (min. €2,872 max. €3,670).
• A year-end bonus of 8.3% and annual vacation pay of 8%.
• High-quality training programs and other support to grow into a self-aware, autonomous scientific researcher. At TU/e we challenge you to take charge of your own learning process.
• An excellent technical infrastructure, on-campus children's day care and sports facilities.
• An allowance for commuting, working from home and internet costs.
• A Staff Immigration Team and a tax compensation scheme (the 30% facility) for international candidates.
