On the fatigue properties of aluminium conductor in dynamic export cables  
Driven by society’s need to tackle climate change, renewable energy generation continues to grow. To reach out for new natural resources, such as wind, wind farms are now more often being installed offshore at sea, further off the coast. In such places, winds blow with much greater force and more frequently than on land. High voltage (HV) subsea dynamic cables are essential elements in the power collection and transmission from offshore wind farms to the shore, thus playing a central role in the renewable energy transition. 

A dynamic cable is usually subjected to a complex loading history during manufacturing, installation and operation. The cable hangs in the water between the offshore wind farm and the seabed and have to withstands severe mechanical stress from currents, waves and the continuous movement of the floating wind farm. Therefore, designing reliable components is essential to prevent mechanical failure which can endanger the operability of the cable. Fatigue properties will be one of the factors that determine the overall performance and operating life of dynamic cables.

Thesis description 
The objective of this thesis work is to build knowledge on the fatigue properties of aluminium conductor in dynamic export cables. The activities will focus on characterizing the fatigue properties of compacted aluminium conductor, taking into account that, during productions, aluminium strands/wires have been subjected to severe plastic deformations due to conductor compaction process.

 The proposed main activities are summarized in the following points:
•    Pre-study and literature survey.
•    3D finite element (FE) modelling and simulation of conductor compaction process,
•    Analysis of the effects of compaction process on the mechanical properties of strands.
•    3D FE modelling and simulation of aluminium conductor subjected to cyclic/fatigue loads.
•    Validation of the numerical FE simulation results to the corresponding experimental data.
•    Write the final report.
In addition, experimental characterization tests will be performed to quantify the fatigue properties (e.g., in terms of fatigue S-N curves), of the compacted conductor strands.

Qualifications and requirements 
The required qualifications are:
•    Master student in Solid Mechanics, Material Science, Engineering Mechanics, Applied Mechanics, Engineering Physics or any related field. 
•    Good knowledge of solid mechanics, material science and finite element method (FEM).
•    Good experience in using FEA commercial software, e.g. Abaqus.
•    Excellent command of spoken and written English.
