  1. 1. Topology Optimization of Fatigue-Constrained Structures

    Författare :Henrik Svärd; Krister Svanberg; Pierre Duysinx; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; topology optimization; fatigue constraints; stress constraints; density filters; restriction methods; weakest link theory; critical plane criteria; Mathematics; Matematik;

    Sammanfattning : Fatigue, or failure of material due to repeated cyclic loading, is one of the most common causes of mechanical failures. The risk of fatigue in a load carrying component is often lowered by adding material, thereby reducing stresses. LÄS MER

  3. 2. Compressive Failure of NCF Composites

    Författare :Anton Shipsha; Magnus Burman; Zuheir Barsoum; Leif Asp; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vehicle and Maritime Engineering; Farkostteknik;

    Sammanfattning : The necessity to reduce environmental impact promotes transportation industry to reduce energy consumption of vehicles. One possible way to improve vehicles' structural efficiency is to utilize modern composite materials that offer excellent mechanical performance-to-weight ratio. LÄS MER

  4. 3. On the fracture behaviour of softwood : a combined experimental and computational study of the interaction between fracture behaviour and material anatomy

    Författare :Lars Olof Jernkvist; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : The propensity for fracture, i.e. failure through separation of the material, is a factor that must be regarded in the design of wooden structures, but also in wood machining operations and drying. LÄS MER

  5. 4. Advanced Antenna Systems for Fully Polarimetric Radar in Automotive Scenario

    Författare :Zhaorui Zang; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; circular polarization; gap waveguide; Antenna; dual circular polarization; automotive radar; polarimetric radar;

    Sammanfattning : The increasing dependence on Advanced Driver Assistance Systems (ADAS) highlights the critical need for fast target recognition, effective collision avoidance, cruise control, lane assistance, etc. This necessitates a significant advancement in sensor technology, particularly for accurate target classification and road surface sensing.
