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

    Detta är en avhandling från Kungliga Tekniska högskolan

    Författare :Annaclaudia Montanino; KTH.; [2020]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Traumatic Brain Injury; Axonal Injury; Mechanoporation; Multiscale;

    Sammanfattning : 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.

  2. 2. Multiscale Modelling of Reinforced Concrete

    Detta är en avhandling från Kungliga Tekniska högskolan

    Författare :Adam Sciegaj; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multiscale; bond-slip; cracking; computational homogenisation; reinforced concrete;

    Sammanfattning : 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. LÄS MER

  3. 3. Multiscale Modelling of Reinforced Concrete Structures

    Detta är en avhandling från Kungliga Tekniska högskolan

    Författare :Adam Sciegaj; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cracking; computational homogenisation; multiscale; bond-slip; reinforced concrete;

    Sammanfattning : 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.

  4. 4. Multiscale Modelling of a Nanoelectromechanical Shuttle

    Detta är en avhandling från Kungliga Tekniska högskolan

    Författare :Caroline Huldt; [2005]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; DFT; Nanoelectromechanics; Mesoscopics; Shuttle; Multiscale;

    Sammanfattning : Nanoelectromechanical systems couple mechanical and electronic degrees of freedom creating a new type of electrical components. The nanoelectromechanical shuttle consists of a double junction with a movable central island. LÄS MER

  5. 5. Analysis and Applications of the Heterogeneous Multiscale Methods for Multiscale Elliptic and Hyperbolic Partial Differential Equations

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Doghonay Arjmand; KTH.; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Multiscale Methods; HMM; Multiscale Wave Equation; Multiscale Elliptic Equation; Long Time Wave Propagation; SRA - E-Science SeRC ; SRA - E-vetenskap SeRC ;

    Sammanfattning : This thesis concerns the applications and analysis of the Heterogeneous Multiscale methods (HMM) for Multiscale Elliptic and Hyperbolic Partial Differential Equations. We have gathered the main contributions in two papers. LÄS MER
