  1. 1. Utdragshållfasthet och styvhet i axiellt belastade skruvinfästningar i korslaminerat trä

    Kandidat-uppsats, Jönköping University/JTH, Byggnadsteknik och belysningsvetenskap

    Författare :Carl Hagvall; Svante Wallin; [2023]
    Nyckelord :KL-trä; skruvförband; skruvinfästningar; styvhet; utdragshållfasthet; utdragsprov;

    Sammanfattning : Introduction – Cross-laminated timber (CLT) is a product that is becoming increasingly common in the construction industry. CLT is categorized as homogeneous or combined, where homogeneous has the same strength classes throughout the entire cross-section and combined has varying strength classes across the cross-section.

  3. 2. Evaluation of a Test Rig to Determine the Need For Human Operators in Ergonomic Testing of Pistol Grip Power Tools

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Felix Ekman; Axel Sernelin; [2023]
    Nyckelord :;

    Sammanfattning : Handheld power tools are found in many different manufacturing processes, everywhere from miniature screw joints in cell phones to safety-critical joints in automotive vehicles. The tools are often used for many consecutive hours which emphasizes the need for good ergonomics to ensure the safety of the operators. LÄS MER

  4. 3. Comparative analysis of contact and non-contact method for determining the natural frequencies of a bolted joint

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Malin Dyberg; Elvira Troillet; [2023]
    Nyckelord :;

    Sammanfattning : To ensure high assembly quality of components, a proper clamping force in bolted joints is essential. The existing tightening technology rely on torque and angle; however, this thesis proposes a method for obtaining the clamping force of a bolted joint based on measuring the natural frequencies.

  5. 4. Utmattning av implantat-förankrade bro-konstruktionermed ett frihängande led och två olika fixturdiametrar. En pilotstudie

    Kandidat-uppsats, Malmö universitet/Odontologiska fakulteten (OD)

    Författare :Ahmed Yassin; Mohammed Al-Haideri; [2023]
    Nyckelord :Cantilever; Dental implants; Fixed dental prosthesis; Fatigue; Fracture strength; Implant angulation; Brotthållfasthet; Dentala implantat; Fast protetik; Frihängande led; Implantatvinkling; Utmattning.;

    Sammanfattning : Purpose: The purpose of this study is to evaluate how implant-supported fixed dental prosthesis (FDP) restorations with a cantilever at abutment level resist fatigue by dynamic loading and thermocycling depending on the fixture diameters.   Material and method: The study involved two groups with three specimens in each group, based on the diameter of the fixture, 3.

  7. 5. Approximating Damping Coefficient of Bolted Joints using the Finite Element Method

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Abhiroop Chatterjee; [2023]
    Nyckelord :;

    Sammanfattning : Bolted joints are important due to their energy dissipation property in structures,but the damping mechanism is also highly nonlinear and localized. The goal ofthis thesis is to develop an accurate method for modeling bolted joint dampingin large structures using finite element (FE) software. LÄS MER
