  1. 1. Evaluation of Coefficient of Friction in Oblique Helmet Impacts: An Experimental and Numerical Study

    University essay from KTH/Hållfasthetslära

    Author : Philip Singh; [2022]
    Keywords : FE model; friction; helmet impact; LS-DYNA; FE-modell; friktion; hjälmislag; LS-DYNA;

    Abstract : 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. 2. Rock Magnetic Studies of Magnetite and Quartzite: Results at Ambient Conditions and From Diamond Anvil Pressure Experiments (~2 GPa)

    University essay from Uppsala universitet/Geofysik

    Author : Dimitra Daniil; [2021]
    Keywords : magnetic susceptibility; remanent magnetization; mDAC; AF demagnetization; NRM; IRM; ARM; magnetisk susceptibilitet; magnetisk remanens; mDAC; AF demagnetisering; NRM; IRM; ARM;

    Abstract : Numerous techniques are used to study the magnetic history and properties of rocks, which provides important data on the Earth’s interior. In this study we conducted a series of experiments on two different sample sets, comprising pure magnetite (Set1) and a mixture of magnetite-hemoilmenite-bearing quartzite (Set2), in order to gather information about their magnetic susceptibility and remanent magnetization.

  4. 3. Minimizing Cooling Time for Diamond Anvil Cell Under High Pressure

    University essay from Lunds universitet/Mekanik

    Author : Martin Edung; [2017]
    Keywords : Diamond Anvil Cell; FEA; FEM; Structural; Transient; Temperature; Ansys; Ansys WB; Machine Drawings; ESS; European Spallation Source; Technology and Engineering;

    Abstract : The main goal of the project was to decrease the cooling time of a diamond anvil cell (DAC) by modifying an existing design. Modifications included change of materials, overall dimensions and a significant reduction of mass together with additional suggestions for decreased cool time. READ MORE

  5. 4. FE-Modelling and Material Characterization of Ice-Hockey Helmet

    University essay from KTH/Skolan för teknik och hälsa (STH)

    Author : Isotta Rigoni; [2017]
    Keywords : traumatic brain injury; ice-hockey; helmet; finite element;

    Abstract : The aim of this research was to produce a reliable finite element model of a helmet, that could be used to simulate approval tests as well as impacts to investigate the safety offered. A 2D and 3D mesh was generated from the CAD file of an Easton Synergy 380 with HyperWorks, and then checked referring to standard parameter values. READ MORE

  6. 5. A self-locking loop as an alternative to purse-string suture in colon anastomosis

    University essay from SLU/Dept. of Clinical Sciences

    Author : Oskar Maxon; [2015]
    Keywords : Colon Anastomosis; self-locking loop; purse-string suture; adaptive anaerobic anastomosis;

    Abstract : Colorectal cancer is among the most common and most deadly cancer types in man. Surgical removal of the tumour is the treatment of choice. Anastomotic leakage is a common and feared complication to this procedure associated with further complications and increased mortality. READ MORE
