Sammanfattning : 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. LÄS MER
Sammanfattning : 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.

Sammanfattning : 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. LÄS MER

Sammanfattning : 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. LÄS MER
