Abstract
The focus of the present paper is on ab initio approaches to the elasticity of materials. First, the methodology to determine single-crystalline elastic constants and polycrystalline moduli of ordered compounds as well as disordered alloys is introduced. In the second part, the methodology is applied on Fe, with a main focus on investigating the influence of magnetism on its elasticity and phase stability and simulating extreme loading conditions that go up to the theoretical tensile strength limits and beyond.
Abstract (in Czech)
Článek se zabývá prvoprincipielními přístupy k elasticitě materiálů. Diskutuje metodologii používanou k výpočtu elastických konstant monokrystalů a jejich středování pro polykrystalické materiály pro uspořádané sloučeniny i neuspořádané slitiny. Metodologie je pak použita ke studiu vlivu magnetismu na elasticitu a fázové transformace v železe a k počítačovým simulacím extrémního mechanického zatěžování na mezi pevnosti.
