  2. 2. Micromechanics of Fiber Networks

    Author : Svetlana Borodulina; Artem Kulachenko; Sören Östlund; Mikael Nygårds; Pierre J.J. Dumont; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Network simulation; Mechanical properties; Fibers; Fiber-to-fiber bonds; Free fiber length; Number of contacts; Contact density; Paper properties; X-ray microtomography; Solid Mechanics; Hållfasthetslära;

    Abstract : The current trends in papermaking involve, but are not limited to, maintaining the dry strength of paper material at a reduced cost. Since any small changes in the process affect several factors at once, it is difficult to relate the exact impact of these changes promptly. READ MORE

  3. 3. Modeling of fracture and damage in rubber under dynamic and quasi-static conditions

    Author : Elsiddig Elmukashfi; Martin Kroon; Krishnaswami Ravi-Chandar; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solid Mechanics; Hållfasthetslära;

    Abstract : Elastomers are important engineering materials that have contributed to the different technical developments and applications since the 19th century. The study of crack growth mechanics for elastomers is of great importance to produce reliable products and therefore costly failures can be prevented. READ MORE

  4. 4. Influence of inhomogeneities on the tensile and compressive mechanical properties of paperboard

    Author : Anton Hagman; Mikael Nygårds; Sören Östlund; Nils Hallbäck; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Paperboard; Inhomogeneities; In-plane properties; Tension; Compression; Shear properties; Delamination; Solid Mechanics; Hållfasthetslära;

    Abstract : The in-plane properties of paperboard have always been of interest to paper scientists. Tensile properties are crucial when the board is fed through converting machines at high speeds. Compressive properties are essential in the later use. Inhomogeneities affect both the compressive and tensile properties. READ MORE

  5. 5. A fixed-lag smoother for solving joint input and state estimation problems in structural dynamics

    Author : Ulrika Lagerblad; Artem Kulachenko; Thomas Abrahamsson; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Joint input-state estimation; Fixed-lag smoother; Structural dynamics; Solid Mechanics; Hållfasthetslära;

    Abstract : In this thesis we have investigated different numerical filters for joint input and state estimation, with the aim of designing a robust algorithm capable of monitoring the continuous motion and loading in a truck chassis. The algorithm has to be able to use sparse measurements of the motion on different parts of the truck as it is excited by road induced vibrations, and transform this data into knowledge of the state in the entire system.
