  1. 1. Microstructure-based Mechanical Behaviour in Structural Analyses of Cast Components

    Author : Jakob Olofsson; Ingvar L. Svensson; Salem Seifeddine; Torsten Sjögren; Högskolan i Jönköping; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Component behaviour; Structural analysis; Mechanical behaviour; Casting process simulation; Finite element method simulation;

    Abstract : In the process of developing cast iron and cast aluminium components, the co-operation between product development and production is important. On the engineering level, this co-operation is limited already in the product development phase e.g. by the lack of established methods to consider the mechanical behaviour of the completed component.

    Abstract : The Swedish truck industry is forced to find new material solutions to achieve lighter engines with increased strength. Customers and new environmental regulations demand both higher specific power and more environmentally friendly trucks, and this places a rising pressure on the manufactures. READ MORE

  3. 3. Micromechanical Modelling of Wood and Fibre Properties

    Author : Kent Persson; Byggnadsmekanik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; Byggnadsteknik; Building construction; Microfibril angle; Density; Hygroexpansion; Stiffness; Simulation; Wood; Fibre; pollution control; Miljöteknik; kontroll av utsläpp; Material technology; Materiallära; materialteknik;

    Abstract : Wood is a material with mechanical properties that vary markedly, both within a tree and among trees. Moisture changes lead to shrinkage or swelling and modify the mechanical properties. READ MORE

  4. 4. A Study on Microstructure-Dependent Deformation and Failure Properties of Boron Alloyed Steel

    Author : Stefan Golling; Larsgunnar Nilsson; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Abstract : Developments in the automotive industry are driven by customer desires and legislative authorities. Legislation has restricted the emissions standards for vehicles, and has mandated the need for higher safety standards. READ MORE

  5. 5. Thin Film and Plasma Characterization of PVD Oxides
