  2. 1. 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

  4. 2. Modelling of cyclic and viscous behaviour of pearlitic steels. Application to tread braked railway wheels

    Author : Ali Esmaeili; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Railway wheels; viscoplasticity; tread braking; rolling contact fatigue; full-scale brake rig testing; finite element analysis; plasticity;

    Abstract : Railway wheel and rail materials are subjected to very high stresses and, in some cases, also elevated temperatures. The rolling contact loading results in a multiaxial stress state with a combination of compression and shear. READ MORE
