PhD Position Microstructural Modelling of Steel Fracture

Make steel more environmentally friendly through advanced fracture analysis

Job description
We are seeking an ambitious PhD candidate who will help us to make steel more environmentally friendly by identifying the effects of recycling on the toughness of the steel.

A prior PhD study developed a statistical model that relates certain aspects of steel microstructure (e.g. grain size, size and properties of subgranular particles) to the low-temperature toughness of the material. In this project, you will extend the work by introducing a microstructurally-informed model for the high-temperature toughness into the same material. You will then update both the low and high temperature toughness models with mechanical behavior of subgranular particles based on their chemical composition. You will work closely with materials scientist within TU Delft, RWTH Aachen and University of Gent and with data scientists at University of Saarland. Your main focus will be in the use of the experimental data from the materials scientists to develop the models and upscaling to macroscopic fracture toughness data in the ductile to brittle transition. While you will work primarily in modelling, direct collaboration with the experimental part is possible (e.g. attending tests), and limited experimentation is possible based on preference.

This project is part of the EU MOWSES project, whose details can be found at https://www.mowses-steel.eu/.

The successful candidate will have a strong background in mechanics and structures. They will not be afraid to engage in writing or editing of material subroutines in FEA software (especially Abaqus), though prior knowledge of material subroutines is not a requirement at the beginning of the project

Job requirements

• You must have a masters degree in mechanical, civil, or materials engineering.
• You must have prior programming experience and be open to learning to develop material subroutines in FEA.
• You must be creative and have an ability to work independently and as part of a team.

TU Delft (Delft University of Technology)

Together, we imagine, invent and create solutions using technology to have a positive impact on a global scale. That is why we invite you to apply. Your application will receive fair consideration.

Challenge. Change. Impact!

Faculty Mechanical Engineering
From chip to ship. From machine to human being. From idea to solution. Driven by a deep-rooted desire to understand our environment and discover its underlying mechanisms, research and education at the ME faculty focusses on fundamental understanding, design, production including application and product improvement, materials, processes and (mechanical) systems.

ME is a dynamic and innovative faculty with high-tech lab facilities and international reach. It’s a large faculty but also versatile, so we can often make unique connections by combining different disciplines. This is reflected in ME’s outstanding, state-of-the-art education, which trains students to become responsible and socially engaged engineers and scientists. We translate our knowledge and insights into solutions to societal issues, contributing to a sustainable society and to the development of prosperity and well-being. That is what unites us in pioneering research, inspiring education and (inter)national cooperation.
