  1. 1. Modelling the viscoplastic properties of carbon black filled rubber : A finite strain material model suitable for Finite Element Analysis

    Author : Rickard Österlöf; Leif Kari; Alan Muhr; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reinforcing fillers; rubber; finite strain; viscoplastic; förstärkande fyllmedel; gummi; finita töjningar; viskoplastisk; Vehicle and Maritime Engineering; Farkostteknik;

    Abstract : An increased environmental awareness, legal demands and the large part of total costs attributable to fuel cost are all incentives for the automotive industry to reduce fuel consumption. The optimal driveline to enable this reduction depends on the operational conditions and the available infrastructure. READ MORE

  2. 2. Flow, expansion and processing behaviours of gas-containing filled polyethylene

    Author : Nabil Khoshaba; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mechanical properties; flow rate; critical pressure; injection moulding; expansion kinetics; fillers; rheological properties; foaming; composite materials; partial pressure; capillary viscometry; Blowing agent;

    Abstract : The utilization of fillers in polymeric materials has exhibited a substantial growth during the last decades. Chalk (calcium carbonate) and glass fibres are two common examples of such fillers. These fillers/reinforcing elements are used in order to reduce the cost of material and change its physical (mechanical) properties. READ MORE

  3. 3. Thermoset polymers and coatings subjected to high compressive loads

    Author : Daniel Ståhlberg; Mats Johansson; Gijsbertus de With; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polymers; organic coating; thermoset; mechanical properties; compression; Surface engineering; Ytbehandlingsteknik;

    Abstract : This study describes the mechanical response of thermoset polymers under high compressive loads. The study is divided into two parts. The first part focuses on the behaviour of a powder coating when used in a clamping force joint and how the properties vary when the chemical and physical structure of the coating is changed.

  4. 4. Modelling of the Fletcher-Gent effect and obtaining hyperelastic parameters for filled elastomers

    Author : Rickard Österlöf; Leif Kari; Per-Erik Austrell; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; filled elastomers; natural rubber; carbon black; Fletcher-Gent effect; Payne-effect; finite strain; hyperelastic;

    Abstract : The strain amplitude dependency , i.e. the Fletcher-Gent effect and Payne effect, and the strain rate dependency of rubber with reinforcing fillers is modelled using a modified boundary surface model and implemented uniaxially. READ MORE

  5. 5. Thermoresponsive cellulose-based composites by polymer modification

    Author : Emma Larsson; Anna Carlmark Malkoch; Lian Hutchings; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Engineering; Kemiteknik;

    Abstract : The interest in utilizing cellulose based materials has grown rapidly in recent years, due to the growing environmental concerns about utilizing fossil based material. One potential application of cellulose is in thermoresponsive materials, which are attracting attention due to their ability of altering conformation when exposed to changes in external temperature.
