  2. 1. History Reduction Techniques for Simulation of Additive Manufacturing and Physically based Material Modeling

    Author : Andreas Malmelöv; Andreas Lundbäck; Bijish Babu; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solid Mechanics; Hållfasthetslära;

    Abstract : 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. READ MORE

  4. 2. Simulation of additive manufacturing using a mechanism based plasticity model

    Author : Andreas Malmelöv; Andreas Lundbäck; Mathias Wallin; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Residual stress; Material model; Alloy 625; Alloy 718; deformations; Finite Element Method; synchrotron X-ray diffraction; Solid Mechanics; Hållfasthetslära;

    Abstract : 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. READ MORE

  5. 3. Finite element modelling and simulation of welding of aerospace components

    Author : Andreas Lundbäck; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material Mechanics; Materialmekanik;

    Abstract : 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. READ MORE

  7. 5. Modelling of Bulk Metallic Glass formation in Powder Bed Fusion

    Author : Johan Lindwall; Andreas Lundbäck; Mattias Unosson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material Mechanics; Materialmekanik;

    Abstract : 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.
