  1. 1. Analysis of Head Kinematics in Ice Hockey

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

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

    Sammanfattning : 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.

  3. 2. Simulation of GPHE diagonal based on full material history

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/Hållfasthetslära

    Författare :Anna Gunnarsson; Jenny Hoang; [2021]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The objectives for this thesis is to further develop a finite element analysis methodology where the material history is evaluated in every step. The processing of the plate from coil to fully formed plate mounted in a heat exchanger should be taken into consideration. Material phenomena such as necking and springback are important to capture.

  4. 3. Studying American Football with Finite Element Analysis and Video Analysis

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Daniel Sliwinski; [2021]
    Nyckelord :Medical Engineering; Helmet to Helmet impacts; Helmet to Ground impacts; Finite Element Analysis; Video Analysis; GHBMC; Maximum Principal Strain; American Football; Medicinsk teknik; Hjälm mot hjälm tackling; Hjälm mot mark tackling; Videoanalys; Finite Element analys; GHBMC; Maximum Principal Strain; Amerikansk fotboll;

    Sammanfattning : Head injuries in American football is a serious issue regarding player health which is highly affected by velocity and its direction. Impact location can affect the severity of the head injury in both helmet-to-helmet impacts and helmet-to-ground impacts hence the understanding of concussive outcome from velocities and impact locations must be improved.

  5. 4. Extraction of tool reaction forces using LS-DYNA and its use in Autoform sheet metal forming simulation

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

    Författare :Esbjörn Zachén; [2019]
    Nyckelord :Sheet Metal Forming; Stamping Die; blank holder; Structural Analysis; Finite Element Simulation;

    Sammanfattning : In product development there is still potential to decrease lead times with faster and more accurate simulations. The objective of this thesis was to study whether Finite Element (FE) simulations using explicit LS-DYNA to extract reaction forces from sheet metal forming tools during forming, could be used to improve existing FE models in sheet metal forming software AutoForm.

  7. 5. Reconstruction of Fall Injuries for Children of Different Ages

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Linda Björgvinsdóttir; [2019]
    Nyckelord :Medical Engineering; Biomechanics; Neuronics; Reconstruction; Falls; Children; LS-Dyna; LS-PrePost; PIPER;

    Sammanfattning : The idea to use finite element (FE) models to reconstruct accidents for humans is becoming more popular the last years. They represent the human body very accurately and indicate well changes in shape, size and biomechanical properties. LÄS MER
