  4. 3. Modelling of muscular force induced by non-isometric contraction

    Författare :Natalia Kosterina; Anders Eriksson; Michael Günther; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Skeletal muscle; Muscular force; Concentric contractions; Eccentric con- tractions; History effect; Force modification; Muscle model; Musculoskeletal model;

    Sammanfattning : The main objective of the study was to investigate and simulate skeletal muscleforce production during and after isometric contractions, active muscle lengtheningand active muscle shortening. The motivation behind this work was to improve thedominant model of muscle force generation based on the theories of Hill from 1938. LÄS MER

  5. 4. Multiscale Modelling of Proximal Femur Growth : Importance of Geometry and Influence of Load

    Författare :Priti Yadav; Elena Gutierrez Farewik; Marco Viceconti; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bone tissue modeling; deformity; biomechanics; osteogenic index; poroelastic material; octahedral shear stress; hydrostatic stress; fluid velocity; octahedral shear strain; MRI; walking; jumping; sedentation; Engineering Mechanics; Teknisk mekanik;

    Sammanfattning : Longitudinal growth of long bone occurs at growth plates by a process called endochondral ossification. Endochondral ossification is affected by both biological and mechanical factors. LÄS MER

  7. 5. Ergonomics risk assessment methods for creating healthy work environments

    Författare :Ida-Märta Rhén; Mikael Forsman; Teresia Nyman; Anna-Lisa Osvalder; KTH; []
