  1. 1. Tendon Healing : Mechanical Loading, Microdamage and Gene Expression

    Författare :Malin Hammerman; Per Aspenberg; Pernilla Eliasson; Ludvig Backman; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Mechanical loading and the inflammatory response during tendon healing might be important for the healing process. Mechanical loading can improve the healing tendon but the mechanism is not fully understood. LÄS MER

  3. 2. Mechanics of microdamage development and stiffness degradation in fiber composites

    Författare :Johannes Eitzenberger; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymeric Composite Materials; Polymera konstruktionsmaterial;

    Sammanfattning : Damage in composites reduces its performance and durability and thus its usefulness. The common subject in all papers presented in the licentiate thesis is distributed microdamage, and the materials of interest are a Hemp/Lignin natural composite and glass/carbon fiber reinforced plastics composites.

  4. 3. Inflammation and tendon healing

    Författare :Parmis Blomgran; Per Aspenberg; Jan Ernerudh; Patrik Danielson; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Tendons heal through three different overlapping phases; the inflammatory, proliferative and remodeling phase. Many studies have investigated what factors influence healing of tendons. However, little was known about inflammation and the immune cells present during Achilles tendon healing by the time this thesis started. LÄS MER

  5. 4. Mechanisms of inelastic behavior of fiber reinforced polymer composites

    Författare :Konstantinos Giannadakis; Lars-Olof Nordin; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

    Sammanfattning : In the present thesis, the sources of linear/non-linear viscoelastic and viscoplastic behaviour in polymer composite materials are under study. The significance of this work is related to the nature of all composite materials. All polymer composites tend to indicate a time-dependent behaviour. This behaviour can be either linear or nonlinear. LÄS MER

  7. 5. Microcracking in fiber composites and degradation of thermo-elastic properties of laminates

    Författare :Mohamed Sahbi Loukil; Janis Varna; Zoubir Ayadi; Peter Lundmark; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymeric Composite Materials; Polymera konstruktionsmaterial;

    Sammanfattning : The macroscopic failure of composite laminates subjected to tensile increasing load is preceded by initiation and evolution of several microdamage modes. The most common damage mode and the one examined in this thesis is intralaminar cracking in layers. LÄS MER
