11 PhD positions in the excellence & sustainability programme of the section Mechanics of Materials of TU/e

Are you an engineering scientist who wishes to contribute to high-tech applications, state-of-the-art modelling or experimentation of advanced sustainable materials across the scales? We are looking for outstanding and enthusiastic PhD candidates, with a proven track record of excellence, to work on a challenging PhD project, in an exciting multidisciplinary team.

Section Mechanics of Materials
The section of Mechanics of Materials (MoM) (www.tue.nl/mechmat) at the department of Mechanical Engineering of Eindhoven University of Technology (TU/e) launched a PhD excellence programme for sustainable materials in 2026 in order to recruit 11 outstanding PhD students. The MoM section is recognized worldwide for its high-level research on experimental analysis, theoretical understanding and predictive modelling of complex thermo-mechanical behaviour (e.g., plasticity, damage, fracture) in engineering materials at different length scales, which emerges from the physics and mechanics of the underlying multi-phase microstructure. An integrated numerical-experimental approach is generally adopted for this goal. A state-of-the-art computing infrastructure is in place for the numerical work in this project.

PhD projects
The PhD projects listed below are embedded in 4 larger programmes:

• Green Steels: The Dutch steel sector faces a major transition. The production, processing, use and recovery of steel is to be made significantly more sustainable by 2030 and completely CO2 neutral by 2050. The programme “Growing with Green Steel” is a plan to achieve this, involving major changes throughout the steel value chain. The section Mechanics of Materials contributes to this plan by studying how the microstructure and resulting properties of green steels are being affected by the new steel processing routes.
• Physics-Based Design of Hydrogen-Resistant Steels: The shift to a hydrogen-based energy system brings a major materials challenge: hydrogen can penetrate steel and make it brittle, leading to sudden failure. This is especially challenging for sustainable (‘green’) steel grades, which exhibit a complex microstructural variability. This programme addresses this challenge using tools at the intersection of materials physics, computational modelling, digitalisation and targeted experiments. Using physics-based models linking microstructural mechanisms to macroscopic behaviour, and informed by experimental characterisation and validation, digital twin frameworks are developed enabling a virtual assessment and optimisation of steel microstructures before they are produced. This programme is therefore essential for the future hydrogen economy.
• Thermal interfaces at cryogenic conditions: Many advanced technologies — like quantum computers, powerful microscopes, and chip-making tools — require extreme cooling. However, the optimal design of cooling systems at cryogenic conditions is hampered by the lack of predictive thermal conductance models at these temperatures. This results in costly trial-and-error development, slows innovation, and ultimately in system designs with suboptimal thermal performance and energy inefficiencies. This programme focuses on the development of multiscale models that will improve our understanding of how microstructural changes in materials and evolving constrained contact conditions at cryogenic temperatures affect thermal and mechanical properties and uses that knowledge to build smarter, quieter, and more energy-efficient cooling systems. These new systems will support better medical imaging, faster computers, and greener high-tech manufacturing.
• Wafer handling: Silicon wafers are the base material for the fabrication of modern electronic devices. To ensure optimal reliability of the adopted lithographic processes, two aspects are important: (i) the surface quality of the silicon wafers needs to meet stringent requirements and (ii) the production environment needs to be absolutely immaculate. Both of these aspects constitute the driving force for extensive investigations of silicon under contact loading conditions in this programme. Typically, the influence of mechanical interaction on silicon wafers is investigated by means of advanced scratch experiments under high-resolution observation, that are essential for gaining an improved mechanistic understanding at the microscopic scale.
