  1. 1. Inflation Mechanics of Hyperelastic Membranes

    Författare :Amit Patil; Anders Eriksson; Arne Nordmark; Reijo Kouhia; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Membrane Mechanics; Inflation; Adhesive Contact; Instabilities; Bifurcation; Limit Point; Teknisk mekanik; Engineering Mechanics;

    Sammanfattning : The applications of inflatable membrane structures are increasing rapidly in the various fields of engineering and science. The geometric, material, force and contact non-linearities complicate this subject further, which in turn increases the demand for computationally efficient methods and interpretations of counter-intuitive behaviors noted by the  scientific community.

  3. 2. Computational Nonsmooth Mechanics

    Författare :Peter W. Christensen; J.A.C. Martins; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis concerns the application of modern methods from the field of mathematical programming for solving certain problems of nonsmooth mechanics. Attention is given to contact problems with friction as well as plasticity problems. LÄS MER

  4. 3. Discrete element modelling of the mechanical behaviour of lithium-ion battery electrode layers

    Författare :Axel Lundkvist; Per-Lennart Larsson; Pär Jonsén; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lithium-ion batteries; mechanical characterisation; simulations; contact mechanics; discrete element method; Litiumjonbatterier; mekanisk karakterisering; simuleringar; kontaktmekanik; diskret elementmetod; Teknisk mekanik; Engineering Mechanics; Solid Mechanics; Hållfasthetslära;

    Sammanfattning : Since their introduction in the late 20th century, lithium-ion batteries have become the leading battery technology for portable devices and electric vehicles due to their high energy density and rechargeability. However, the increasing demand for a longer battery life span is hindered by the fading of the battery’s charge capacity over prolonged use. LÄS MER

  5. 4. The One-Dimensional Turbulence Model Applied to Spray Atomization

    Författare :Amirreza Movaghar; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Primary breakup; Turbulence; One Dimensional Turbulence ODT ;

    Sammanfattning : Numerical simulation of the spray behavior is an important part of engine research and is critical for combustion optimization. Successful implementation of the advanced modeling tools for sprays is strongly dependent on our current understanding of the physical processes involved. LÄS MER

  7. 5. Impact of Icing on Wind Turbines Aerodynamic

    Författare :Narges Tabatabaei; Michel Cervantes; Barakos George N.; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : Wind energy covered 11.6% of Europe electricity demand in 2017. Region with cold climates represent a strong potential for wind energy companies because of their sparse population and proper wind conditions. The global wind energy installations in cold climate regions is forecasted to reach a capacity of 186 GW by the end of 2020. LÄS MER
