  2. 21. On the relationship between microstructure, process parameters and mechanical properties of boron steels

    Author : Erik Lundholm; Jörgen Kajberg; Andreas Lundbäck; Paul Åkerström; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Abstract : The continuous development of the press hardening technology has led to stronger, lighter and more environmentally friendly components. Utilising the varying properties of boron steel at different temperatures enables great design freedom, while also attaining high strength in the final component. READ MORE

  4. 22. 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. 23. An Approach on Material Model Calibration for Modelling of Sheet Metal Deformation and Failure

    Author : Stefan Marth; Hans-Åke Häggblad; Mats Oldenburg; Jörgen Kajberg; Odd Sture Hopperstad; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Abstract : Sheet metals are often used in automotive and aerospace applications for safety-relevant components. Weight reduction is one possibility to reduce fuel consumption or increase the payload capacity and therewith reduce the carbondioxide emission of these trans-portation vehicles. READ MORE

  6. 24. Microstructure and property models of alloy 718 applicable for simulation of manufacturing processes

    Author : Marie Anna Moretti; Lars-Erik Lindgren; Paul Åkerström; Jörgen Kajberg; Bijish Babu; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material characterisation; Material modelling; Alloy 718; Plasticity; Recrystallization; Hållfasthetslära; Solid Mechanics;

    Abstract : This thesis focuses on experimental characterization, understanding and modelling of nickel-based alloy 718, for a large range of loading conditions. Alloy 718 is the most widely used nickel-based superalloy, due to its high strength, high corrosion resistance and excellent mechanical properties at high temperatures. READ MORE
