  1. 1. Metal film growth on weakly-interacting substrates : Multiscale modeling

    Author : Víctor Gervilla Palomar; Kostas Sarakinos; Georgios Almyras; Davide Giuseppe Sangiovanni; Michael Tringides; Linköpings universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY;

    Abstract : Thin films are nanoscale layers of material used to functionalize surfaces or to serve as building blocks in more complex devices. In recent years, thin metal films have become vital for modern devices within, e.g. READ MORE

  2. 2. Definition of axonal injury tolerances across scales : A computational multiscale approach

    Author : Annaclaudia Montanino; Svein Kleiven; Alessandra Villa; Xiaogai Li; Kacy Cullen; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Traumatic Brain Injury; Axonal Injury; Mechanoporation; Multiscale;

    Abstract : Traumatic brain injury (TBI) is today regarded as a global health challenge. Revealing how external mechanical loads translate into tissue and cellular damage is necessary, not only for the development of better preventive measures, but also for the definition of treatments that could spare the patients from suffering TBI's devastating consequences.

  3. 3. Multiscale Modelling of Reinforced Concrete

    Author : Adam Sciegaj; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; multiscale; bond-slip; cracking; computational homogenisation; reinforced concrete;

    Abstract : Since concrete cracks at relatively low tensile stresses, the durability of reinforced concrete structures is highly influenced by its brittle nature. Cracks open up for ingress of harmful substances, e.g. chlorides, which in turn cause corrosion of the reinforcement. READ MORE

  4. 4. Homogenization of Partial Differential Equations using Multiscale Convergence Methods

    Author : Pernilla Johnsen; Liselott Flodén; Anders Holmbom; Marianne Olsson Lindberg; Jens Persson; Niklas Wellander; Mittuniversitetet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; homogenization theory; two-scale convergence; multiscale convergence; very weak multiscale convergence; evolution multiscale convergence; very weak evolution multiscale convergence; linear parabolic problems; linear hyperbolic-parabolic problems;

    Abstract : The focus of this thesis is the theory of periodic homogenization of partial differential equations and some applicable concepts of convergence. More precisely, we study parabolic problems exhibiting both spatial and temporal microscopic oscillations and a vanishing volumetric heat capacity type of coefficient. READ MORE

  5. 5. Multiscale Modelling of Reinforced Concrete Structures

    Author : Adam Sciegaj; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; cracking; computational homogenisation; multiscale; bond-slip; reinforced concrete;

    Abstract : Concrete cracks at relatively low tensile stresses; cracks open up for ingress of harmful substances, negatively affecting the durability of reinforced concrete structures. Crack widths are thus limited in the design codes, and accurate predictions are needed, especially for large reinforced concrete structures such as bridges or nuclear reactor containment buildings.
