1. 1. Finite Element Modeling of the Human Head

   Författare :Svein Kleiven; KTH; []
   Nyckelord :Finite element method FEM ; Human head; brain; head injury; epidemiology; statistics; simulations.;

   Sammanfattning : The main objectives of the present thesis were to define the dimension of head injuries in Sweden over a longer period and to present a Finite Element (FE) model of the human head which can be used for preventive strategies in the future. The annual incidence of head injuries in Sweden between 1987 and 2000 was defined at over 22 000, cases most of which were mild head injuries. LÄS MER

3. 2. An Average Female Head-Neck Finite Element Model with Reflexive Neck Muscles

   Författare :I Putu Alit Putra; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Finite Element; Human Body Model; Whiplash Injury; Active Neck Muscle;

   Sammanfattning : Several factors potentially contribute to the risk of whiplash injuries; one of them is the neck muscle activities. Muscle activities in the neck have been shown to influence the head-neck kinematics during whiplash-like rear impacts. LÄS MER

4. 3. Generation of Patient Specific Finite Element Head Models

   Författare :Johnson Ho; Svein Kleiven; Michael Gilchrist; KTH; []
   Nyckelord :Injury Prevention; Patient Specific; Finite Element Head Model; Anatomical Structures; TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : Traumatic brain injury (TBI) is a great burden for the society worldwide and the statisticsindicates a relative constant total annual rate of TBI. It seems that the present preventativestrategies are not sufficient. To be able to develop head safety measures against accidents ine.g. LÄS MER

5. 4. Nonlinear Numerical Simulations of Interactions Between Ice Rubble and Structure

   Författare :Aniket Patil; Andrzej Cwirzen; Björnar Sand; Lennart Fransson; Knut Vilhelm Høyland; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ice mechanics; ice rubble; sea ice ridges; punch through test; shear box test; friction coefficient; cohesive element method; smoothed particle hydrodynamics; continuous surface cap model; numerical modelling; Byggkonstruktion; Structural Engineering;

   Sammanfattning : This research is focused on three distinct but interconnecting topics:1) investigation of physical and mechanical properties of ice rubble, 2) material modelling of ice rubble, 3) numerical simulation of the interaction between ice rubble structure interaction. large scatter in the values of physical and mechanical properties of ice rubble can be seen in the literature due to non-standardised methods.

7. 5. Development of an Anisotropic Finite Element Head Model for Traumatic Brain Injury Prediction

   Författare :Chiara Giordano; Svein Kleiven; Songbai Ji; KTH; []
   Nyckelord :Axonal Strain; Brain Anisotropy; Traumatic Brain Injury; Finite Element Analysis; Brain Tissue; Constitutive Modeling.; Medical Technology; Medicinsk teknologi;

   Sammanfattning : Traumatic brain injury (TBI) is a worldwide health care problem with very high associatedmorbidity and mortality rates. In particular, the diagnosis of TBI is challenging: symptomsoverlap with other pathologies and the injury is typically not visible with conventionalneuroimaging techniques. LÄS MER
