    Abstract : This doctoral thesis concerns flanking transmission in light weight, wooden multi-storey buildings within the low frequency, primarily 20-120 Hz. The overall aim is to investigate how the finite element method can contribute in the design phase to evaluate different junctions regarding flanking transmission. READ MORE

  4. 2. Microsphere-based modeling of electro-active polymers

    Author : Sara Thylander; Hållfasthetslära; []
    Keywords : ;

    Abstract : Elektroaktiva polymerers (EAPs) främsta egenskap är deras förmåga att kunna omvandla elektrisk energi till mekanisk energi (och vice versa). Den typ av EAPs som behandlas inom ramen för detta arbete kallas för dielektriska elastomerer och är en undergrupp av elektroniska elektroaktiva polymerer. READ MORE

  5. 3. Modeling and simulation of electro-viscoelastic polymers

    Author : Anna Ask; Hållfasthetslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electroactive polymers; dielectric elastomer actuators; electromechanical coupling; finite elements; viscoelasticity; finite deformations;

    Abstract : The electroactive polymer materials considered in this work react to electric stimuli by producing deformations. In some cases, the electrically induced deformations are moderate, while in other cases they can be very large and the specimen is stretched to more than twice its original length. READ MORE
