  1. 1. Numerical Assessment of Defects Effect on Boltless Composites Longitudinal Joints

    University essay from KTH/Lättkonstruktioner

    Author : Mara Santaniello; [2020]
    Keywords : ;

    Abstract : The work presented in this thesis focuses on the numerical assessment of defects effect on potential boltless design for fuselage panels longitudinal joints, typically identified as High Load Transfer (HLT) configuration. Nowadays, the state-of-art joining technique for primary aircraft composite structures, such as fuselage barrels, is still mechanical fastening. READ MORE

  3. 2. Techniques for Improving Weldability and Testing of Weld-bonded Joints

    University essay from KTH/Maskinkonstruktion (Inst.)

    Keywords : Adhesives; Automotive industry; Resistance Spot Welding; RSW; Weldability; Weld-bonding; Welding parameters; Fordonsindustri; Limning; Limpunktsvetsning; Motståndssvetsning; Punktsvetsning; Svetsbarhet; Svetsparametrar;

    Abstract : Increased understanding of improving the weld-bonding process is essential in order for the automotive industry to constantly develop their designs and production processes for the energy-efficient vehicles of the future. The joining method of weld-bonding, a hybrid method of adhesive joining and resistance spot welding, has introduced new challenges in the manufacturing and design of auto bodies. READ MORE

  4. 3. Assessment of static performance of LKAB´s welded mesh : Laboratory testing and analysis

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Fredrik Eriksson; [2020]
    Keywords : ;

    Abstract : Surface support is an areal support, which is installed on rock excavation surface to prevent bulking of rock mass and retain loose rock fragments. Welded wire mesh is one type of surface support. Literature study indicates that there is a wide range of testing methods on mesh. READ MORE

  5. 4. Fatigue analysis of welded joints in a forestry machine : Utilizing the notch stress concept

    University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT); Linnéuniversitetet/Institutionen för byggteknik (BY)

    Author : Martin Nyström; Tainan Pantano Tomaz; [2015]
    Keywords : Weld; Fatigue; Finite Element Method; Hot-Spot Method; Notch Stress Method; Structural Dynamics; Forestry Crane; Svets; Utmattningslivslängd; Finita-elementmetoden; Hot-spot; Notch-stress; Notch-spänning; Strukturdynamik; Skogsmaskinskran;

    Abstract : Welding is one of the most applied technics in the world for joining steel. Welds are liable to the phenomenon of fatigue, which is, primarily, the formation of a crack and consequently reduction of strength due to the action of time varying loads. Fatigue is one of the main causes of failure in steel structures. READ MORE

  6. 5. Fatigue life assessment of potential weld improvement techniques using 3D fracture analysis

    University essay from KTH/Lättkonstruktioner

    Author : Nikola Mrdjanov; [2014]
    Keywords : ;

    Abstract : This thesis work was done in conjunction with the VINNOVA-funded research and development project LIGHTSTRUCT. It was performed in the department of lightweight structures at KTH. The thesis investigated two potential weld improvement techniques called toe weaving and extended leg. READ MORE
