PhD on Multi-physics modelling of long-term degradation behavior of composite liners

Are you inspired by the challenge of linking continuum mechanics with chemical and physical degradation? Join our research on modeling the aging of polymer liners under coupled thermal, hygral, and pH-dependent effects.

Information
In this PhD position, you will dive deep into one of the key challenges in modern civil and materials engineering: predicting the long-term performance of fiber-reinforced polymer composites used as a liner in concrete sewer systems. You will develop a cutting-edge, multi-physics numerical model to describe how chemical and mechanical degradation—driven by acidity, moisture, and mechanical loading—affects the structural integrity of these composites over time. Your work will shed light on complex processes such as chain scission, hygroscopic swelling, and polymer-concrete interfacial failure, all under varying environmental conditions like humidity and temperature.

You will be part of the Applied Mechanics chair of the Department of the Built Environment at the Eindhoven University of Technology (TU/e), Netherlands, working closely with experimentalists and modelers to calibrate and validate your model with dedicated lab experiments. The PhD project is part of the EU-funded initiative AI:LINER – Data-Driven Sewer Asset Management, under the HORIZON-CL4-2024-TWIN-TRANSITION-01-12 programme, which brings together 13 participants and 15 associated partners from across Europe to advance the assessment, repair, and long-term resilience of civil engineering infrastructure. Your results will contribute to a broader study on the performance and lifetime of liner-sewer systems, helping municipalities and engineers design longer-lasting and more sustainable underground infrastructure.

This research has high societal relevance: it supports the development of cost-effective, durable materials that are critical to maintaining safe and sustainable public utilities in the face of aging infrastructure and climate change.

We welcome candidates from diverse backgrounds and encourage applicants who are enthusiastic, curious, and driven by impact. At TU/e, you will find a supportive and collaborative research environment where you can grow as both a scientist and a professional.

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