First-Principles Calculations to Investigate the Third-Order Elastic Constants and Mechanical Properties of Mg, Be, Ti, Zn, Zr, and Cd

<div>Brittleness and ductility as functions of pressure. The material is ductile when the ratio is below the critical value of 0.5, and the material is considered brittle when the ratio G/B is larger than 0.571. The five-pointed star, triangle-right, circle, triangle-up, diamond, and square represent Mg, Be, Ti, Zn, Zr, and Cd, respectively.</div>
