Project 1: Thermo-metallurgical modelling for AM processes
The project will focus on the thermo-metallurgical coupling for additive manufacturing (AM) process simulation at melt-pool and at component scale level. Direct-Energy-Deposition (DED) will be used as the main AM technology. The key objective is to develop a numerical model to predict the microstructure evolution including phases, grain size and mechanical properties induced by the thermal cycles due to the AM process. Moreover, its relationship with the material strength will be investigated.
Project 2: Thermo-mechanical modelling of WAAM process
Wire arc additive manufacturing (WAAM) is a directed energy deposition (DED) AM process that uses an electric arc as a heat source to melt a wire feedstock. The WAAM process is capable of producing thin-walled components and is relevant for many industries, such as aerospace, automotive and marine. This PhD project will focus on the thermo-mechanical modelling linking the processing parameters and resultant mechanical properties and defect formation.
Project 3: Modelling of multi-material L-PBF process
Multi-material additive manufacturing using laser-based powder bed fusion (L-PBF) has the potential to disrupt the manufacturing of multi-material parts and enable local tailoring of mechanical and functional properties. In this PhD project, the candidate will develop thermomechanical models to investigate the formation of interfaces and study the complex melt flow in metal-metal composites.
