  2. 1. Modelling, Simulation and Experimental Investigation of a Rammer Compactor Machine

    Author : Anders Jönsson; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Compaction; Non-linear Dynamics; Theoretical Modelling; Numerical Simulation; Experimental Verification; Complete Approach;

    Abstract : This licentiate thesis considers the modelling, simulation and experimental investigation of a rammer compactor machine. The purpose is to develop an efficient and verified method for simulation of rammer compactor machines to be used in the product development process. READ MORE

  4. 2. Micromechanics of Powder Compaction

    Author : Erik Olsson; Per-Lennart Larsson; Christophe Martin; KTH; []
    Keywords : Hållfasthetslära; Solid Mechanics;

    Abstract : Compaction of powders followed by sintering is a convenient manufacturing method for products of complex shape and components of materials that are difficult to produce using conventional metallurgy. During the compaction and the handling of the unsintered compact, defects can develop which could remain in the final sintered product. READ MORE

  5. 3. Discrete element simulation of elasto-plastic shock waves in high-velocity compaction

    Author : Muhammad Shoaib; Leaf Kari; Bruska Azhdar; Wim Desmet; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; High-velocity compaction; Discrete element method; Plastic deformaiton; dynaimic loading; elasto-plastic shock wave; Friction; Adhesion; Physics; Fysik; Järnvägsgruppen - Ljud och vibrationer; Järnvägsgruppen - Ljud och vibrationer;

    Abstract : Elasto-plastic shock waves in high-velocity compaction of spherical metal particles are the focus of this thesis which consists of four papers (A-D). The compaction process is modeled by a discrete element method while using elastic and plastic loading, elastic unloading and adhesion at contacts. READ MORE

  6. 4. Cold compaction of composite powders

    Author : Olle Skrinjar; Per-Lennart Larsson; Alan Cocks; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; micromechanical modelling; composite powders; descrete element method; Engineering mechanics; Teknisk mekanik;

    Abstract : Powder compaction is a production method commonly used in the manufacturing industry today. In order to minimize costly experiments and to optimize serial production of details several methods to analyze the powder compaction process are developed and used. READ MORE

  7. 5. Ultra high-pressure compaction of powder

    Author : Sven Berg; Javier Oliver; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Abstract : Sintering at high-pressure improves the properties of the material, either through new sintering aids becoming available or through improving intergranular bonding. This gives the manufactured products potential advantages like faster cut rates, and more precise and cleaner production methods that add up to cost efficiency and competitive edge. READ MORE
