  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 :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 error controlled atomistic-to-continuum modeling with application to graphene monolayers

    Författare :Arash Memarnahavandi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Quasi-Continuum; stress-free; atomistic-to-continuum; homogenization; adaptivity;

    Sammanfattning : In order to consider virtual materials, i.e. materials that are not manufactured yet, it can be advantageous to model physical phenomena on a lower length scale than the macroscopic one. In such a case, homogenization (or coarse-graining) can be a useful tool. LÄS MER

  4. 3. Optimization in Continuum Flow Problems

    Författare :Niclas Wiker; Anders Klarbring; Thomas Borrvall; Ole Sigmund; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid mechanics; Continuum flow problem; Fluid mechanics; Strömningsmekanik;

    Sammanfattning : The work presented in this dissertation was carried out at the Division ofMechanics, Department of Management and Engineering at Link¨oping University,between 2003 and 2008. It was supervised by Prof. LÄS MER

  5. 4. Continuum modelling of work hardening in precipitation hardened alloys

    Författare :Philip Croné; Jonas Faleskog; Peter Gudmundson; Norman Fleck; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solid Mechanics; Hållfasthetslära;

    Sammanfattning : This thesis deals with prediction of macroscopic work hardening in a precipitation hardened alloy. The focus is on the particle contribution. A hierarchical modelling approach is adopted where work hardening in a representative material volume on the microscale is homogenized and used to represent the macroscopic hardening. LÄS MER

  7. 5. Continuum modelling of composites consolidation

    Författare :Maciej Wysocki; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This work describes the consolidation of commingled yarn-based thermoplastic composites. The consolidation operation involves deformation of the preform, wetting and compaction of fibre bundles, and resin flow through the preform. LÄS MER
