2. 11. Asymptotics and dynamics in first-passage and continuum percolation

   Author : Daniel Ahlberg; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; first-passage percolation; noise sensitivity; continuum percolation; Gilbert model; limit theorems; shape theorem; stopped random walks; large deviations; dynamical percolation; continuum percolation;

   Abstract : This thesis combines the study of asymptotic properties of percolation processes with various dynamical concepts. First-passage percolation is a model for the spatial propagation of a fluid on a discrete structure; the Shape Theorem describes its almost sure convergence towards an asymptotic shape, when considered on the square (or cubic) lattice.

4. 12. Multiphase continuum modeling of wood : A hybrid mixture theory approach

   Author : Winston Mmari; Björn Johannesson; Lynn Schreyer; Linnéuniversitetet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Moisture transport; Coupled heat and moisture; Over-hygroscopic; Hybrid mixture theory; Mixture theory; Swelling; Hygro-mechanical; Non-linear elasticity; Large deformation; Phase field crack model; Anisotropic cracking; FEM; Numerical model; Norway spruce; Wood; Porous media; Forestry and Wood Technology; Skog och träteknik;

   Abstract : Wood has been used as a construction material for a very long time. The development of efficient industrial production processes of wood has expanded the use of the material with the introduction of new products, such as engineered wood products. READ MORE

5. 13. On the continuum muscle modeling

   Author : Babak Sharifimajd; Jonas Stalhand; Anders Klarbring; Martin Kroon; Linköpings universitet; []
   Keywords : ;

   Abstract : Modeling muscle behavior using techniques developed in continuum mechanics is a growing eld of research. The developed models allow for a more generalized way of computing stresses and deformations, specially, when it comes to using nite element techniques. READ MORE

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

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

   Abstract : 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. READ MORE

7. 15. Continuum modelling of composites consolidation

   Author : Maciej Wysocki; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : 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. READ MORE
