1. Analys av huvudkinematik under olyckor i alpina slalomdisciplinen : -med stöd från videoanalysverktyg
Uppsats för yrkesexamina på grundnivå, Mittuniversitetet/Institutionen för ingenjörsvetenskap, matematik och ämnesdidaktik (2023-)Sammanfattning : Huvudskador inom alpin skidsport är bland de allvarligaste skador som kroppen utsätts för. Tidigare studier på huvudskador som genomförts på grenar såsom Störtlopp, Super-G, Storslalom, Skicross, Freestyle och Snowboard visar att standarder som finns på skyddsutrustning inte är tillräckliga.

2. Evaluation of Coefficient of Friction in Oblique Helmet Impacts: An Experimental and Numerical Study
Master-uppsats, KTH/HållfasthetsläraSammanfattning : The focus of this thesis was to increase the knowledge in the area of "dynamic friction" during oblique helmet impacts, both experimentally and numerically. Physical experiments have been performed with multiple helmets, different angles of the anvil and different surface materials, with results of impact forces from the anvil and accelerations of the head.

3. Analysis of Head Kinematics in Ice Hockey
Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)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.

4. Linear Impact of Bicycle Helmet – Experimental Testing and FE-modelling
Master-uppsats, KTH/HållfasthetsläraSammanfattning : The aim with this master thesis was to set up a FE-simulation of an impact test of a bike helmet in LS-DYNA that correlates well with the peak acceleration score of a real life impact test. Furthermore, a parametric study has been performed in LS DYNA to investigate the robustness of the model, as well as to see which parameters have a great influence on the peak acceleration score.

5. Investigating the Potential of Jaw Protection to Reduce the Risk of Concussions in Ice Hockey : A Finite Element Study
Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Sammanfattning : Ice hockey is a sport with high velocities and a large number of impacts to the head. The high occurrence of concussions is being recognized, and both short and long term consequences have been found. LÄS MER
