  1. 21. 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.

  3. 22. 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.

  4. 23. Study of non-linear strain path in sheet metal forming

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Chandramohan Aisvaran; [2021]
    Nyckelord :;

    Sammanfattning : At present, Sheet Metal Forming (SMF) is not just limited to increasing demand from automobile industries but also to various other manufacturing industries that utilize sheet metal forming processes. The surplus demands for optimised manufacturing products warrant the need for an extended decisive study on SMF. LÄS MER

  5. 24. Analysis of the Potential of Different Foam Materials in Face Protection to Reduce the Risk of Concussions in Ice Hockey

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

    Författare :Annika Neumann; [2021]
    Nyckelord :Ice Hockey Jaw Protection; FEM; Concussion; Foam;

    Sammanfattning :  Ice hockey players are at a high risk to sustain a concussion. Most of the concussion-inducing hits are to the jaw region, nevertheless, most players do not wear any protective gear shielding the jaw. LÄS MER

  7. 25. Numerical modelling for characterization of the granular flows impact on the gas flow in a packed-bed-reactor

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Anton Sundström; [2020]
    Nyckelord :DEM; Discrete element method;

    Sammanfattning : The goal of the project was to characterize the granular flows impact on the gas flow in a packed-bed-reactor. The study was created at Swerim as a master's thesis for Luleå University of Technology. The packed-bed-reactor geometry used in this study is a scaled down blast furnace model. LÄS MER
