  1. 6. Finite Element Procedures in Modelling the Dynamic Properties of Rubber

    Författare :Anders K Olsson; Byggnadsmekanik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; akustik; vibration and acoustic engineering; Materiallära; materialteknik; Mechanical engineering; hydraulics; vacuum technology; Material technology; dynamic; amplitude; frequency; Technological sciences; Teknik; FEM; rubber; vibrationer; vakuumteknik; Maskinteknik; hydraulik;

    Sammanfattning : Rubber is not only a non-linear elastic material, it is also dependent on strain rate, temperature and strain amplitude. The non-linear elastic property and the strain amplitude dependence give a non-linear dynamic behavior that is covered by the models suggested in this thesis. LÄS MER

  3. 7. Tableting performance of dry granulated particles : Significance and assessment of compression mechanical properties

    Författare :Maryam Tofiq; Göran Alderborn; Ann-Sofie Persson; Josefina Nordström; Peter Kleinebudde; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dry granulation; Powder compression; Compression parameters; Granule composition; Granule structure; Granule strength; Granule fragmentation; Granule deformation; Tablet tensile strength; Loss of tabletability;

    Sammanfattning : Dry granulation (DG) is often utilized as an intermediate process during tablet manufacturing, for improving flow characteristics of the powder blend and/or reducing segregation issues related to the active pharmaceutical ingredient (API). The resulting granules exhibit typically irregular shapes with rough surfaces and their mechanical properties are related to the feeding powder and the process parameters used during the DG. LÄS MER
