  1. 6. Simulations of experimental crack development in ceramic material with notched specimen

    University essay from KTH/Hållfasthetslära

    Author : Clas Dahlin; [2022]
    Keywords : Solid Mechanics; Fracture mechanics; Ceramics; Dynamics; Ballistics; Hållfasthetslära; Brottmekanik; Keramer; Dynamik; Ballistik;

    Abstract : Low-density armour often uses ceramic materials, as their high compressive strength and relatively low weight make the material ideal for moving in the field. The ballistic protection works by redirecting the plastic flow of the projectile radially, which reduces penetration. READ MORE

  2. 7. Applicability of Graph Neural Networks to predict Human variability in Human Body Model Rib Strain Predictions

    University essay from Uppsala universitet/Statistik, AI och data science

    Author : Julia Solhed; [2022]
    Keywords : Graph Neural Networks; Human Body Model; SAFER HBM; HBM simulation; Rib strain predictions; Rib fracture risk predictions;

    Abstract : Finite element human body models have in recent years become widely used in the area of vehicle safety evaluations. They make it possible to predict injury risk in specific areas, down to the organ level in the human body. An existing human body model, SAFER HBM includes a rib cage representing an average male.

  3. 8. Improved side impact car safety : New IIHS side crash regulation, effect on product design

    University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Author : Andreas Bäckman; [2022]
    Keywords : Side impact beam; IIHS; side crash; side impact crash testing; crash testing of automobiles; industrial design engineering; automotive design; product design; Sidokrockskydd; IIHS; sidokrock; sidokollision; sidokrocktestning; krocktest av bilar; teknisk design; bildesign; produktdesign;

    Abstract : 23% of passenger vehicle occupant deaths in 2019 was side-impact collisions and is a ongoing problem that continues to take people’s lives (IIHS, 2021a). IIHS (Insurance Institute for Highway Safety) is an organization based in USA, which performs vehicle crash tests with the goal of making cars safer and reducing deaths and injuries. READ MORE

  4. 9. Material Characterization and Blade Impact Simulation

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Gustaf Bodare; [2022]
    Keywords : Strain rate dependency; Split-Hopkinson pressure bar; Digital image correlation; LS-DYNA; FEM; SPG;

    Abstract : Blades used on brushcutters and lawn mowers are subjected to a wide variety of working conditions. Besides continuous loads from cutting grass, the blades are also subjected to accidental impacts of branches, stones and structures. READ MORE

  5. 10. Analysis of Head Kinematics in Ice Hockey

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : David Pogosian; [2022]
    Keywords : Ice hockey; Video analysis; MPS; THUMS; Concussion; Head kinematics; Finite Element analysis; Ishockey; Videoanalys; MPS; THUMS; Hjärnskakning; Huvudkinematik; Finita element metoden;

    Abstract : Ice hockey has been identified as a sport with a high risk for concussions due to it being highly physical. Improvements have been made over the years to improve the protective gear for the players effectively eliminating more severe traumatic brain injuries (TBIs) however mild concussions (mTBI) are still prevalent to this day.
