  2. 2. Identification of Viscoelastic Materials by Use of Wave Propagation Methods

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Saed Mousavi; Uppsala universitet.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering physics; Identification; Viscoelastic; Complex modulus; Complex Poisson s ratio; wave; Impact; Teknisk fysik; TECHNOLOGY Engineering physics; TEKNIKVETENSKAP Teknisk fysik;

    Abstract : Complex moduli and Poisson’s ratio have been estimated using extensional and torsional wave experiments. The data were used for assessment of linearity and isotropy of two polymers, polymethyl methacrylate (PMMA) and polypropylene (PP). The responses of both materials were found to be close to linear and isotropic. READ MORE

  3. 3. Micromechanics of Fiber Networks

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Svetlana Borodulina; Artem Kulachenko; Sören Östlund; Mikael Nygårds; Pierre J.J. Dumont; [2016]
    Keywords : 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

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

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Elsiddig Elmukashfi; Martin Kroon; Krishnaswami Ravi-Chandar; [2015]
    Keywords : 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

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

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Anton Hagman; Mikael Nygårds; Sören Östlund; Nils Hallbäck; [2016]
    Keywords : 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
