  1. 1. Fracture simulation with a hyperelastic phase field model

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Adrien Fradet; [2023]
    Nyckelord :Fracture; Phase field modeling; Hyperelasticity; Brott; fasfält-methoden; hyperelasticite;

    Sammanfattning : The phase field method is a versatile tool to study crack initiation and propagation in systems with complex geometries. Based on a variational formulation of the equilibrium equations, the sharp crack topology is regularized by a crack with diffusive edges and the damage is described by a continuous phase field variable.

  3. 2. Applying spatially and temporally adaptive techniques for faster DEM-based snow simulation

    Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Författare :Simon Andreasson; Linus Östergaard; [2023]
    Nyckelord :Real-time simulation; DEM; GPU; Games; Computer graphics; Realtidssimulering; DEM; GPU; Spel; Datorgrafik;

    Sammanfattning : Background. Physically-based snow simulation is computationally expensive and not yet applicable to real-time applications. Some of the prime factors for this cost are the complex physics, the large number of particles, and the small time step required for a high-quality and stable simulation. LÄS MER

  4. 3. Urban Planning for Better Air Quality : A case study of the Low-Traffic Neighbourhoods in London

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Greta Gustafsson; [2022]
    Nyckelord :Low-Traffic Neighbourhoods; London; Green Infrastructure; Urban Planning; Air Pollution;

    Sammanfattning : Air pollution affects the environment negatively, boosts climate change, and is the cause of millions of deaths per year, first and foremost affecting the people living in urban areas. Since the early 20th century, many cities have been planned around cars, which are the main contributors to the bad air quality. LÄS MER

  5. 4. Framtagning av ett chassi med upphängningssystem till en sexhjulig autonom leveransrobot

    M1-uppsats, KTH/Hållbar produktionsutveckling (ML)

    Författare :Afram Racho; [2022]
    Nyckelord :Mechanical design; Mobile robot platform; Chassis; Suspension; Product development; TerraGo Deliveries; Mekanisk design; Mobilrobotplattform; Chassi; Upphängningssystem; Produktframtagning; TerraGo Deliveries;

    Sammanfattning : En växande medvetenhet om miljöfrågor i kombination med den ökade produktiviteten och effektiviteten som skapas av automation och digitalisering har lett till ett växande intresse för autonoma leveransrobotar. TerraGo Deliveries utvecklar eldrivna autonoma leveransrobotar med fokus på matleveranser. LÄS MER
