4. 2. Finite Element Procedures in Modelling the Dynamic Properties of Rubber

   Author : Anders K Olsson; Byggnadsmekanik; []
   Keywords : 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;

   Abstract : 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. READ MORE

5. 3. Machining properties of wood : Tool wear, cutting force and tensioning of blades

   Author : Luis Cristovao; Luleå tekniska universitet; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

   Abstract : Cutting processes, in general, and wood cutting processes, in particular, are complex to explain and describe with many influencing factors. Wood, in contrast to man-made fabricated materials, is not a homogenous and distinct material, but a multifaceted and nonhomogeneous biological material. READ MORE

6. 4. Floor vibration : dynamic properties and subjective perception

   Author : Fredrik Ljunggren; Luleå tekniska universitet; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk akustik; Engineering Acoustics;

   Abstract : This thesis covers research in the floor vibration field. Although lightweight steel framed constructions have been in focus, many results are applicable to floors in common and to some extent also to vibrations in general. READ MORE

7. 5. Tool steel for tool holder applications : microstructure and mechanical properties

   Author : Anna Medvedeva; Jens Bergström; Birger Karlsson; Karlstads universitet; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; tool steel; tool holder; microstructure; mechanical properties; machinability; Materials science; Teknisk materialvetenskap;

   Abstract : Large improvements in cutting tool design and technology, including the application of advanced surface engineering treatments on the cemented carbide insert, have been achieved in the last decades to enhance tool performance. However, the problem of improving the tool body material is not adequately studied. READ MORE
