1. History Reduction Techniques for Simulation of Additive Manufacturing and Physically based Material Modeling
Sammanfattning : In this thesis, finite element (FE) simulations of additive manufacturing (AM) and physically based material modeling are presented. AM is a process where the component is built layer-wise. LÄS MER
2. Simulation of additive manufacturing using a mechanism based plasticity model
Sammanfattning : This thesis presents finite element (FE) simulations of additive manufacturing (AM) and physically based material modeling of alloy 625 and alloy 718. In recent years, there has been an increasing interest in AM and there has been a dramatic increase in publications in the field. LÄS MER
3. Finite element modelling and simulation of welding of aerospace components
Sammanfattning : Fusion welding is one of the most used methods for joining metals. This method has largely been developed by experiments, i.e. trial and error. LÄS MER
4. Modelling and simulation of welding and metal deposition
Sammanfattning : Fusion welding is one of the most used methods for joining metals. This method has largely been developed by experiments, i.e. trial and error. LÄS MER
5. Modelling of Bulk Metallic Glass formation in Powder Bed Fusion
Sammanfattning : This thesis discusses a model for simulation of the Powder Bed Fusion (PBF) process of metallic powder with the capability to become amorphous. The temperature field in the PBF process is predicted by a three-dimensional thermal finite element model in three dimensions using a layer-by-layer approach, meaning that the scanning strategy of the moving laser spot is consolidated into a single heat source acting on the entire layer momentarily.
