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 stationary expressions of Young’s modulus are obtained. For three stationary values of Young’s modulus,...
