Insulating concrete is a material designed to reduce heat conduction with pores/insulations, and these pores strongly affect the material characteristics. In general, the insulation effect is directly proportion to the pore volume, while the material strength decreases as the porosity increases. To overcome this contrary, anisotropic insulations with different spatial distributions are proposed...

This paper presents a forward calculation and analytic results of plate wave propagation in stressed plates of cubic materials. The single crystalline Ge films deposited on the Z-cut silicon wafers are investigated. Significant biaxial residual stresses in the film results from the lattice misfit between of the Ge film and the Si substrate. Phase velocity change of the acoustic waves due to mec...

In this paper instability of planar anisotropic sheet metal during a few forming processes is investigated for the first time. For this reason components of the constitutive tangent tensor for planar anisotropic sheets are developed. By using the above tensor location of necking is predicted. Direction of the shear band is also predicted using the acoustic tensor. A finite element program is pr...

We report on first principles calculations of the anisotropy of the intrinsic spin Hall conductivity (SHC) in nonmagnetic hcp metals and in antiferromagnetic Cr. For most of the metals of this study we find large anisotropies. We derive the general relation between the SHC vector and the direction of spin polarization and discuss its consequences for hcp metals. Especially, it is predicted that...

Ah&act--It is shown that in solid mechanics a skin effect is associated with anisotropy. Near a free surface or a surface of discontinuity certain components of the stress field vary rapidly from zero to a maximum within a thin skin. The thickness of this skin tends to vanish for increasing anisotropy. A stress concentration also occurs whereby certain stress components are amplified within the...

We compare our photoemission spectra with the calculated energy spectra of oxygen vacancies in Ta oxide to identify the defects responsible for the formation of a band in the gap of a Ta oxide-based memristor. We have previously explained transitions between high and low resistance states in a memristor conducting channel under bias reversal by accumulation and depletion of oxygen in the channe...

A microscopic expression of the residual electrical resistivity tensor is derived in linear response theory for Rashba electrons scattering at a magnetic impurity with cylindrical or noncylindrical potential. The behavior of the longitudinal and transversal residual resistivity is obtained analytically and computed for an Fe impurity at the Au(111) surface. We studied the evolution of the resis...

composites provide design flexibility because many of them can be moulded into complex shapes.  carbon fibre-reinforced epoxy composites exhibit excellent fatigue tolerance with high specific strength and stiffness. these properties led to their numerous advanced applications ranging from military and civil aircraft structures to consumer products. the modelling of beams undergoing arbitrarily ...

In this work it is shown that there are some spatially homogeneous but anisotropic models (Kantowski-Sachs and Bianchi type-III), with a positive cosmological constant, for which the inhomogeneities in the distribution of matter on the surface of the last scattering produce anisotropies (in large angular scales θ ∼ > 10 ◦) that do not differ from the ones produced in Friedmann-Lemâıtre-Robertso...
