    Abstract : Today, crash simulations replace crash testing in the product development phase in theautomotive industry. High quality simulations enable shorter product development time andhigher competitiveness. READ MORE

  4. 7. Hip fractures : A biomechanical analysis of fracture strength prediction, prevention, and repair

    Author : Joeri Kok; Avdelningen för Biomedicinsk teknik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Finite element; Bone cement; Femur; Fracture; Experimental mechanics; X-ray imaging;

    Abstract : Due to the aging population, hip fracture incidence has been increasing over the past decades. Measurements of bone mineral density with dual energy X-ray absorptiometry are the gold standard for hip fracture risk assessment, where patients with a low bone density have a high risk of fracture.

  5. 8. Numerical simulations of blast loaded steel plates for improved vehicle protection

    Author : Björn Zakrisson; Gerald Nurick; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Abstract : In the past decade, there has been an increasing demand from governments for high level protections for military vehicles against explosives. However, the design and validation of protection is a time consuming and expensive process, where previous experience plays an important role. READ MORE

  6. 9. Mechanical Characterization of Heterogeneous Brittle Materials

    Author : Laura Suarez; Pär Jonsén; Jörgen Kajberg; Simon Larsson; Lars-Olof Nordin; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Abstract : Comminution is one of the highest energy-consuming processes in the mining and mineral processing industry by consuming around 2% of the global generated energy with an overall efficiency of 1-3%. Different approaches to the optimization of processes have been developed, but there is still room for improvement. READ MORE

  7. 10. Methods for mechanical testing based on analysis of elastic waves in rods

    Author : Janne Carlsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Abstract : This thesis summarizes six papers on development and applications of a method to evaluate the normal force and particle velocity at any cross-section of a nonuniform rod from measurements of strain at two different cross-sections. In Paper A the method is developed. It is an extension of that developed by Lundberg and Henchoz for uniform rods. READ MORE
