PhD position on Polymeric Friction for Offshore Industry Applications

Job description

The ongoing 4th industrial revolution (Industry 4.0) will continue experiencing an evolving trend, marked by the exponential growth of additive manufacturing, and an increasing demand of customization of the manufactured products. However, the manufacturing sector needs to meet unpostponable sustainability guidelines and criteria. This means minimizing the energy losses as much as possible. To fully sustain this ongoing transition, two key technical challenges need to be simultaneously tackled: the uncertainty induced to the product by the production process (e.g. human errors, geometrical and material variabilities caused by the manufacturing process and/or by the machine setup) and the increasing complexity of the manufactured goods, especially if they are the critical parts or components. The ambition of APRIORI is to develop new technologies that will enable for the first time the development of a unique integrated product design strategy that will drastically improve the performance of critical parts or components under uncertainties.

This doctoral project is part of a larger, multidisciplinary and international project APRIORI: “Active PRoduct-to-Process LearnIng fOR Improving Critical Components Performance” (no. 101073551) funded under the Marie-Sklodowska-Curie Actions Doctoral Networks within the Horizon Europe Programme of the European Commission. APRIORI gathers universities (KU Leuven, TU Delft, Aalborg University), research institute (Jozef Stefan Institute) and small- and large-scale industry (Grundfos Holding AS, Materialise NV, Temporary Works Design 9 B.V., Qlector) from manufacturing, equipment design, manufacturing software and data-driven solutions sectors. The APRIORI mission is to train the next generation of doctoral candidates regarding the uncertainty induced by the production process (e.g. human errors, geometrical and material variabilities caused by the manufacturing process and/or by the machine setup) and the increasing complexity of the manufactured goods characterized by their critical parts or components.

APRIORI is set to offer 10 doctoral candidates the organizational framework and resources necessary for undertaking high-impact research within a multidisciplinary and international network, involving academic and practice partners from Belgium, Slovenia, Denmark and the Netherlands. In addition to their research activities, the doctoral candidates will participate in peer-educational initiatives, further enhancing the collaborative and scholarly dimensions of the program.

Your involvement in this project concerns the investigation of the tribological and frictional performance of polymeric surfaces sliding against coated steel surfaces. Specifically, you will focus on the understanding and prediction of the transition from stick to slip behaviour. The research is framed within the context of offshore industry friction-based connections used in mission equipment on offshore wind installation vessels. Currently, there is a lack of high-fidelity guidelines for the design, characterization and selection of these friction-based support elements. To fill this gap, you will develop testing and predictive models to quantify the friction force variability with reference to the interface features, such as interfacial stiffness, roughness, hardness and other material, environmental, and operational properties. Potential friction models will be sought within the direction of physics-informed probabilistic models, by integrating aspects of contact mechanics, tribology and acquired experimental data.

The project is embedded in a cross-departmental collaboration within the faculty of Civil Engineering and Geosciences, including the Department of Mechanics, Materials, Management and Design (3MD), the Department of Hydraulic Engineering (HE) and the Department of Engineering Structures (ES).
