  1. 1. On the mechanics of actin and intermediate filament networks and their contribution to cellular mechanics

    Författare :Björn Fallqvist; Kroon Martin; Peter McHugh; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; actin; cell; mechanical; constitutive; intermediate; continuum; constitutive; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : The mechanical behaviour of cells is essential in ensuring continued physiological function, and deficiencies therein can result in a variety of diseases. Also, altered mechanical response of cells can in certain cases be an indicator of a diseased state, and even actively promoting progression of pathology. LÄS MER

  3. 2. On crack growth under compressive stresses

    Författare :Per Isaksson; Mittuniversitetet; []

    Sammanfattning : This thesis concerns fractures subjected to compressive stresses. In the four papers appended fracture behavior in brittle as well as ductile materials is studied. LÄS MER

  4. 3. Impact damping and airplane towing : two studies of the response of solid bodies to transient loads

    Författare :Carlos Matuk; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : The impact of a linearly elastic hammer on a linearly viscoelastic plate is the first problem considered in this thesis. The results, obtained by using the Laplace transformation method, can be used in the design of impact protection devices. LÄS MER

  5. 4. On fiber network fracture mechanics and kink band formation in biocomposites

    Sammanfattning : This thesis summarizes seven appended papers dealing with: (1) The fracture of fibrous materials, e.g. LÄS MER

  7. 5. Modeling of structural integrity of aged low alloy steels using non-local mechanics

    Författare :Magnus Boåsen; Pål Efsing; Jacques Besson; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : Ageing of low alloy steels affects the structural integrity assessment as it most commonly causes embrittlement and a hardening of the material. This is due to theevolution of the microstructure during operation in the specific application. LÄS MER
