  1. 1. Transmission of waves through elastic and viscoelastic junctions

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Tomas Nygren; Uppsala universitet.; [1998]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Wave; elastic; viscoelastic; extensional; characteristic impedance; junction; transmission; reflection; dissipation; optimisation; Materialvetenskap; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap; Solid Mechanics; hållfasthetslära;

    Abstract : Transmission of extensional waves through elastic and viscoelastic junctions between elastic and collinear bars have been studied theoretically and experimentally. The models used can be interpreted also for other types of waves (e.g. dilatational waves, shear waves, electromagnetic waves) and systems. READ MORE

  2. 2. Elastic Neutron Scattering at 96 MeV

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Joakim Klug; Uppsala universitet.; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nuclear physics; neutron; detection; CsI; elastic scattering; differential cross section; optical potential; kerma; Kärnfysik; NATURAL SCIENCES Physics Nuclear physics; NATURVETENSKAP Fysik Kärnfysik; Applied Nuclear Physics; Tillämpad kärnfysik;

    Abstract : A facility for studies of elastic neutron scattering in the 50–130 MeV range has been developed. In addition to elastic neutron scattering, it has been used for (n,p) and (n,d) reaction experiments. The performance of the device has been illustrated in measurements of the (n,p) and (n,n) cross sections on 1H and 12C. READ MORE

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Kondenserade materiens fysik; Condensed matter physics; Mesoskopisk fysik; Mesoscopic physics;

    Abstract : This thesis concerns describing the mechanical properties of the two dimensional material graphene by continuum elasticity theory. In particular, Nano ElectroMechanical Systems (NEMS) where part of the graphene sheet is made suspended, are considered. READ MORE

  5. 5. Numerics of Elastic and Acoustic Wave Motion

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Kristoffer Virta; Uppsala universitet.; Uppsala universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; finite differences; stability; high order accuracy; elastic wave equation; acoustic wave equation; Beräkningsvetenskap med inriktning mot numerisk analys; Scientific Computing with specialization in Numerical Analysis;

    Abstract : The elastic wave equation describes the propagation of elastic disturbances produced by seismic events in the Earth or vibrations in plates and beams. The acoustic wave equation governs the propagation of sound. READ MORE
