  2. 1. On error controlled atomistic-to-continuum modeling with application to graphene monolayers

    Author : Arash Memarnahavandi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Quasi-Continuum; stress-free; atomistic-to-continuum; homogenization; adaptivity;

    Abstract : In order to consider virtual materials, i.e. materials that are not manufactured yet, it can be advantageous to model physical phenomena on a lower length scale than the macroscopic one. In such a case, homogenization (or coarse-graining) can be a useful tool. READ MORE

  4. 2. Modeling Residual Stress Fields in Soft Tissues : with Application to Human Arteries

    Author : Tobias Olsson; Linköpings universitet; []
    Keywords : Continuum Mechanics; Modeling; Residual Stress; Soft Tissues; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Biomechanics or Mechanics of Biology comprises many different fields. This thesis deals with soft tissues or living tissues and the fact that these materials live in a pressurized environment. This means that an unloaded tissue may not be stress free. The stress in an unloaded body is usually called residual stress. READ MORE

  5. 3. Mechanical Properties of Arteries : Identification and Application

    Author : Jan-Lucas Gade; Jonas Stålhand; Carl-Johan Thore; Håkan Johansson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : In this Licentiate of Engineering thesis, a method is proposed that identifies the mechanical properties of arteries in vivo. The mechanical properties of an artery are linked to the development of cardiovascular diseases. READ MORE

  6. 4. Soft Tissue Mechanics with Emphasis on Residual Stress Modeling

    Author : Tobias Olsson; Anders Klarbring; Ray W. Ogden; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mechanics; Residual Stress; Growth; Remodeling; Engineering mechanics; Teknisk mekanik;

    Abstract : This thesis concerns residual stress modeling in soft living tissues. The word living means that the tissue interacts with surrounding organs and that it can change its internal properties to optimize its function. READ MORE

  7. 5. Modelling the passive mechanical properties of arteries

    Author : Jonas Stålhand; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis concerns the modelling of passive mechanical properties of arteries. An artery is characterised by large nonlinear deformation, anisotropy and incompressibility. In addition, it is subjected to a residual stress when the applied load is removed. All this combined makes it complex to derive appropriate mechanical models. READ MORE
