The Extreme Values of Young’s Modulus and the Negative Poisson’s Ratios of Rhombic Crystals
The extreme values of Young’s modulus for rhombic (orthorhombic) crystals using the necessary and sufficient conditions for the extremum of the function of two variables are analyzed herein. Seven
Strong Elastic Anisotropy of Low-Dimensional Ternary Compounds: InXTe3 (X = Si, Ge)
The stability, anisotropic elastic behavior and electronic properties of trigonal In2Si2Te6, InSiTe3, In2Ge2Te6, and InGeTe3 compounds have been studied by first-principles calculations. The

Expressions are given for the maximum and minimum values of Poisson's ratio ν for materials with cubic symmetry. Values less than −1 occur if and only if the maximum shear modulus is associated with
The anisotropy of Young's modulus, shear modulus and Poisson's ratio in cubic materials
The directional behaviour of Young's modulus, shear modulus, and Poisson's ratio are expressed for a number of crystallographic planes for cubic materials. Their behaviour as a function of direction
