  1. 1. Transverse anisotropy in softwoods Modelling and experiments

    University dissertation from Stockholm : KTH

    Author : Carl S. Modén; Lars Berglund; Lennart Salmén; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Softwood; Cellular solid; Anisotropy; Deformation mechanisms; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap;

    Abstract : Transverse anisotropy is an important phenomenon of practical and scientific interest. Although the presence of ray tissue explains the high radial modulus in many hardwoods, experimental data in the literature shows that this is not the case for pine. READ MORE

  2. 2. Fatigue Anisotropy in Forged Components

    University dissertation from Stockholm : KTH

    Author : Cornelius Temmel; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Inclusion Cluster; Low Sulfur; Machinability; Inclusion; Manganese Sulfide; Quenching Crack; Forging; Isotropic Quality; Steel; Anisotropy;

    Abstract : Ever-growing requirements on combustion engine efficiency of motor vehicles demand increasing service loads in powertrain components. Optimization of component material is therefore inevitable. A major detriment with many forged transmission components is their anisotropic mechanical behavior, not least during cyclic loading.

  3. 3. Determination of Coefficient of Friction and Anisotropy in Metalworking

    University dissertation from Stockholm : Industriell produktion

    Author : Han Han; [2003]
    Keywords : Coefficient of Friction; anisotropy; flow stress; modified two-specimen method MTSM and FE-analysis;

    Abstract : The work material in metal working operations always showssome kind of anisotropy. To simplify the theoretical analysis,anisotropy is usually neglected and the material is assumed tobe isotropic, especially in determination of coefficients offriction. READ MORE

  5. 5. On the modeling of large ratcheting strains and anisotropy in pearlitic steel

    University dissertation from Institutionen för anläggning och miljö

    Author : Göran Johansson; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Large strains; Plasticity; Anisotropy; Ratcheting; Kinematic hardening;

    Abstract : Thermodynamically consistent constitutive material models for describing the large strain response of polycrystalline metals are proposed. Emphasis is put on the multiaxial ratcheting under cyclic loading and the evolution of anisotropy in pearlitic steel. READ MORE
