    Sammanfattning : The ability to control the path a signal takes through microwave circuitry is crucial when designing RF systems. The component that allows for the control of the signal path is called a switch, and it is the microwave component that this thesis will focus on. LÄS MER

  3. 2. Numerical analysis of a bearing strength in delaminated composite joint

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Olavi Kukkonen; [2023]
    Nyckelord :Bearing strength; Single-lap shear; Delamination; Countersinking; Hole size;

    Sammanfattning : Composite structures are commonly joined using adhesive or mechanical joints, withmechanical joints being preferred when components need to be removable for maintenancepurposes. However, the presence of mechanical joints introduces a discontinuity in theload path, which can serve as an initiation point for failure and needs to be taken intoaccount in the design of the joint.
