Crystal structures and elastic properties of superhard IrN2 and IrN3 from first principles
TL;DR: In this paper, first principles calculations were performed to investigate the structural, elastic, and electronic properties of IrN2 for various space groups: cubic Fm-3m and Pa-3, hexagonal P3(2)21, tetragonal P4(2)/mnm, orthorhombic Pmmn, Pnnm, and Pnn2, and monoclinic P2(1)/c.

Density functional theory for calculation of elastic properties of orthorhombic crystals: Application to TiSi2
TL;DR: In this article, a theoretical formalism to calculate the single crystal elastic constants for orthorhombic crystals from first principle calculations is described, and the elastic constants using a full potential linear muffin-tin orbital method using the local density approximation (LDA) and generalized gradient approximation (GGA).

The intrinsic thermal conductivity of AIN
TL;DR: The thermal conductivity of AIN has been measured from 0.4 to 1800 K as discussed by the authors, and it has been shown that the heat conduction is by phonons and that at the lowest temperatures the phonon mean-free-path, l, is limited by boundary scattering.

The Elastic Properties of Composite Materials
TL;DR: In this paper, the problem of determining the elastic properties of composite materials (polycrystals, polycrystals and porous or cracked solids) is approached in several ways, via scattering theory, through variational principles, or by the assumption of specific geometries for the material under consideration.
