  2. 1. 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

  5. 3. Simulation of heat generation in elasto-plastic materials

    Author : Paul Håkansson; Hållfasthetslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The demand for improved models for simulation of mechanical problem is today very great, especially since today's computer capacity makes it possible to simulate large and complicated problems. In some applications, temperature effects and the heat generated from inelastic deformation can not be neglected in order to achieve a good accuracy of the simulation. READ MORE

  6. 4. Modeling of evolving anisotropy at finite elasto-plastic strain

    Author : Magnus Harrysson; Hållfasthetslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Simulation tools are used to a wide extent in the product development process today, both to obtain better products and to reduce the development time required. Anisotropic materials are utilized in many engineering applications. READ MORE

  7. 5. Cam Roller Contact : Surfaces and Tribology

    Author : Frédéric Cabanettes; Bengt-Göran Rosén; Ulf Olofsson; Högskolan i Halmstad; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wear reduction; camshaft; roller; surface topography; relocation; elasto plastic rough contact; elasto hydrodynamic lubrication; Mechanical engineering; Maskinteknik;

    Abstract : The automotive industry and the design of engines are strongly ruled by performance and legislation demands. In the valve train, mechanical components such as camshafts and rollers are defined by specifications including more and more constraints concerning their ability to face wear thus prolonging lifetime.
