Homogenization in strength and durability analysis of reinforced tooth filling [PDF]

, 2002
An asymptotic homogenization procedure is employed to obtain effective elastic properties of the composite tooth filling, a homogenized macro– stress field and a first approximation to the micro-stress field, from properties of the components and applied

Finite temperature elastic constants of paramagnetic materials within the disordered local moment picture from ab initio molecular dynamics calculations

, 2016
We present a theoretical scheme to calculate the elastic constants of magnetic materials in the high-temperature paramagnetic state. Our approach is based on a combination of disordered local moments picture and ab initio molecular dynamics (DLM-MD ...

Layered metal carbo–selenide Nb2CSe2 with van der Waals interlayer coupling

Journal of Advanced Ceramics
The stacking structure of Nb2CSe2, a newly synthesized layered metal carbo-selenide, was elucidated by scanning transmission electron microscopy. Nb2CSe2 features Se−Nb−C−Nb−Se quintuple atomic layers. These layers are stacked in Bernal mode.

PROPERTIES OF THE ANISOTROPIC ELASTICITY TENSOR [PDF]

The Quarterly Journal of Mechanics and Applied Mathematics, 1989
Summary: A unified presentation of some properties of the fourth-rank tensor of anisotropic elasticity is given. The unified presentation involves both established concepts such as the Cauchy relations, the Voigt and Reuss bounds, planes of symmetry and specific directions of longitudinal wave propagation, and a new concept, the specific axis for pure ...
