Nous rendons compte ici d'une méthode de calcul de l'équation d'état et des courbes Hugoniot des métaux simples sous haute compression, à la fois dynamique et statique. La méthode est fondée sur l'observation que les énergies libres de Helmholtz des phases isochoriques solide et liquide diffèrent surtout par leurs composantes entropiques respectives. Par conséquent, nous utilisons une théorie pseudopotentielle au second ordre pour calculer les fonctions thermodynamiques du métal simple par une méthode variationnelle qui traite la phase solide, à des fins structurelles, comme un liquide supra-refroidi. Dans le cas de l'aluminium, nous avons examiné des compressions de volume de l'ordre de V/V0≈1/3, correspondant aux valeurs atteintes dans de...
