2. 1. Transverse anisotropy in softwoods : Modelling and experiments

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

4. 2. Fatigue Anisotropy in Forged Components

   Author : Cornelius Temmel; Chalmers University of Technology; []
   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.

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

   Author : Han Han; KTH; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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 to be isotropic, especially in determination of coefficients of friction. READ MORE

6. 4. Scale dependency, hetrogeneity and anisotropy of surface roughness of rock fractures

   Author : Nader Fardin; KTH; []
   Keywords : Rock fracture; Roughness; Heterogeneity; Anisotropy; Fractals; Stationarity; Roughness length method; Statistical analysis; Erroranalysis; 3D-laser scanning;

   Abstract : .... READ MORE

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

   Author : Göran Johansson; Chalmers University of Technology; []
   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
