  2. 6. Residual stresses in paperboard and the influence of drying conditions

    Author : Magnus Östlund; Sören Östlund; Douglas Coffin; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; paper; drying; mechanical properties; residual stress; curl;

    Abstract : The drying sequence in the manufacturing process for paperboard involves evaporation of water, primarily from within the fibres. The vapour is then transported out of the web by pressure or concentration gradients. READ MORE

  4. 7. Tailored process gases for laser powder bed fusion

    Author : Camille Nicole Géraldine Pauzon; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Helium; Laser powder bed fusion; AM process productivity; Spatter particles; Residual oxygen; 316L stainless steel; Argon; Nitrogen; Additive manufacturing; Process atmosphere; Process stability; Residual stresses.; Ti-6Al-4V; Alloy 718;

    Abstract : Metal laser powder bed fusion (L-PBF) allows for production of complex components using the energy from a laser to locally melt micron-sized powder following a layer-wise approach. Considerable scientific efforts are focused on addressing the influence of the process parameters on the melting stability and the control of material properties, while developing necessary monitoring and characterization tools.

  5. 8. Residual Stress in Additive Manufacturing : Control using orientation and scan strategies

    Author : Prabhat Pant; Ru Peng; Johan Moverare; Kjell Simonsson; Thomas Niendorf; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive manufacturing; Residual stress; Neutron diffraction; FEM; Scan strategies; Build orientations;

    Abstract : Components with complex features that are designed with their function as a core aspect often are not viable to be manufactured with traditional methods. This has been a bottleneck in the past, leading to heavier parts with various sub-assemblies and a significant waste of material. READ MORE

  6. 9. Robustness Analysis of Residual Stresses in Castings

    Author : Magnus Hofwing; Niclas Strömberg; Mårten Olsson; Linköpings universitet; []
    Keywords : ;

    Abstract : This thesis is about robustness analysis of residual stresses in castings. This topic includes the analysis of residual stresses in castings and the robustness analysis itself, both covered in the thesis. Residual stresses are important when designing casted components. READ MORE

  7. 10. Modeling of residual stresses in dental composites

    Author : Philippe Lingois; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

    Abstract : In several European countries, dental composites are replacing mercury- containing amalgams as the most common restorative materials. The problems with dental composites are that they can induce pain for the patient, fracture in the tooth, and gaps between the tooth and the filling which will induce secondary caries. READ MORE
