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 ...

Elastic Deformation of Polycrystals

, 2002
We propose a framework to model elastic properties of polycrystals by coupling crystal orientational degrees of freedom with elastic strains. Our model encodes crystal symmetries and takes into account explicitly the strain compatibility induced long ...

Elastic properties of superconducting MAX phases from first principles calculations

, 2010
Using first-principles density functional calculations, a systematic study on the elastic properties for all known superconducting MAX phases (Nb2SC, Nb2SnC, Nb2AsC, Nb2InC, Mo2GaC and Ti2InC) was performed. As a result, the optimized lattice parameters,

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 ...
