Stationary Points of Poisson’s Ratio of Six-Constant Tetragonal Crystals AT Particular Orientations
摘要
Abstract
The present study analyzes stationary points and values of Poisson’s ratio of six-constant tetragonal crystals for particular cases and orientations using Euler’s angles parametrization. Poisson’s ratio stationary values, points coordinates and their kind are obtained with use of well-known experimental data on elasticity coefficients. Analysis on angular dependencies of Poisson’s ratio performed for several crystals.
