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. Linear and Nonlinear Mechanics of Lattice Materials : Computational Modelling and Experiments

   Författare :Danial Molavitabrizi; Mahmoud Mousavi; Kristofer Gamstedt; Haiyang Yu; Samuel Forest; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk fysik med inriktning mot tillämpad mekanik; Engineering science with specialization in Applied Mechanics;

   Sammanfattning : Lattice materials are artificial materials made of repeating unit-cells. The internal architecture of these materials can be engineered for a specific application such as energy absorption, heat transfer, or acoustic damping. LÄS MER

4. 3. Automated Computational Modeling

   Författare :Johan Jansson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; multi-adaptivity; Galerkin; ODE; PDE; plasticity; elasticity; FEM; automated;

   Sammanfattning : This thesis is part of the FEniCS project of Automation of Computational Mathematical Modeling (ACMM) as the modern manifestation of the basic principle of science:formulating mathematical equations (modeling) and solving equations (computation). The vision of FEniCS is to set a new standard towards the goals of generality, efficiency, and simplicity, concerning mathematical methodology, implementation, and application. LÄS MER

5. 4. 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

7. 5. Computational topology optimization in continuum mechanics

   Författare :Thomas Borrvall; Martin P. Bendsøe; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : This dissertation concerns theoretical and computational methodologies in topology optimization in continuum mechanics.A general procedure for treating problems of this kind starts with the establishment of a well-posed continuum problem formulation, in the sense that one can prove existence of at least one solution to the problem.
