2. 1. Engineering rubber bushing stiffness formulas including dynamic amplitude dependence

   Author : Maria-José Garcia; Leif Kari; Anders Ågren; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Construction engineering; Konstruktionsteknik;

   Abstract : Engineering design models for the torsion and axial dynamic stiffness of carbon black filled rubber bushings in the frequency domain including amplitude dependence are presented. They are founded on a developed material model which is the result of applying a separable elastic, viscoelastic and friction rubber component model to the material level. READ MORE

4. 2. Magneto-sensitive rubber in the audible frequency range

   Author : Peter Blom; Leif Kari; Luigi Bregant; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Magneto-sensitivity; Rubber; Audible frequency range; Amplitude dependence; Vibration isolator; Fletcher-Gent effect; Stiffness; Acoustics; Akustik;

   Abstract : The dynamic behaviour in the audible frequency range of magneto-sensitive (MS) rubber is the focus of this thesis consisting of five papers A-E. Paper A presents results drawn from experiments on samples subjected to different constant shear strains over varying frequencies and magnetic fields. READ MORE

5. 3. 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

6. 4. Modeling of Elasticity and Damping for Filled Elastomers

   Author : Per Erik Austrell; Byggnadsmekanik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rheological models; contact-free strain measurement; modified hardness test; solid dumbbell test specimen; mechanical conditioning; strain energy plot; hyperelasticity; carbon-black-filled rubbers; amplitude dependence; multiaxial viscoplastic model; Building construction; Byggnadsteknik;

   Abstract : Elasticity and damping are significant properties of rubber, taken advantage of in engineering applications. It is therefore important that the constitutive model accurately captures these aspects of the mechanical behavior. READ MORE
