MTL member Emmanouil L. Papazoglou successfully defends his PhD Thesis
MTL member Emmanouil L. Papazoglou has successfully defended his PhD thesis titled: “Methodology for microscale modeling of the SLM process by using FEM”.
The main novel contributions of his work can be summarized as:
- Development and validation of a 3D thermal model with an uncomplicated volumetric heat source that efficiently simulates and predicts the geometrical characteristics of the melt pool under Conduction Mode.
- Development and validation of a 3D thermal model that utilizes deformed geometry feature to model and simulate the geometrical characteristics of the melt pool under Conduction, Transition and Keyhole Modes considering the material ablation.
- Reduction of the 3D thermal model to a 2D thermal model for a quicker estimation of the material ablation rate and the main geometrical characteristics of the melt pool.
- Proposed a possible approach to simulate the different material phases (solid – semiliquid – liquid) when the fluid dynamics equations are integrated and solved by a thermohydraulic model.
Three excellent papers have already been published from this work.
