Propagation of elastic waves through textured polycrystals: application to ice

The propagation of elastic waves in polycrystals is revisited, with an emphasis on configurations relevant to the study of ice. Randomly oriented hexagonal single crystals are considered with specific, non-uniform, probability distributions for their major axis. Three typical textures or fabrics (i.e. preferred grain orientations) are studied in detail: one cluster fabric and two girdle fabrics...

Determination of Hashin-Shtrikman bounds on the isotropic effective elastic moduli of polycrystals of any symmetry

Although methods to determine optimal Hashin–Shtrikman bounds for polycrystals of cubic to monoclinic symmetry have been described, the calculation of bounds for triclinic crystals has not previously been possible. The recent determination of elastic moduli of common minerals with low symmetry provides motivation to extend the Hashin–Shtrikman formulation to lower symmetry. Here, Hashin– Shtrik...

Homogenization methods for anisotropic linear elastic polycrystals

The elastic properties of uniform polycrystalline materials without defects depend on both the constitutive properties of the constituents and the microstructural characteristics like the distribution of grain orientations and grain shapes. For an overview concerning the homogenization of elastic properties see, e.g., [1]. The elementary bounds by Voigt and Reuss take into account only the volu...

Paramagnetic properties of NdFeAsO0.94F0.06 polycrystals

The temperature and field dependencies of magnetization of NdFeAsO0.94F0.06 bulk sample are shown to exhibit the Curie-Weiss behaviour, both in the superconducting and normal states. To address the origin of the strong paramagnetic signal, particularly to reveal contributions from antiferromagnetic second phases in sintered NdFeAsO0.94F0.06, the magnetic response of Nd2O3 was measured and compa...

Exact relations for effective moduli of polycrystals

Composite materials play an increasingly important role in our everyday life and technology from skis and golf clubs to sensors and actuators in high tech components. By “composite” we mean a perfectly bonded homogeneous mixture of two or more materials on a length scale much smaller than human size and much larger than interatomic distances. The physical properties of a composite (conducting, ...
