We show that elastic moduli of higher (third and fourth) order of prestressed single crystals at high pressure, obtained from the Gibbs free energy, enter the relation between the Cauchy stress and Lagrange finite-strain tensor the same way they do f

At high pressures (the pressure is comparable with the bulk modulus) the crystalline lattice may become unstable relative to the uniform shear deformations, and in a result the low symmetric crystalline structures will appear (the so-called “elasti

Crystalline lattices can become unstable to uniform shear strains, which may lead to a structural transformation to less symmetric structures. Transitions of this type are called elastic phase transitions. In this paper, elastic phase transitions in
