2008-7-29 A simple theoretical model is developed to investigate the temperature dependence of elastic constants. The method is based on a new expression for the temperature dependence of the bulk modulus and the formulation derived from Tallon’s model. The proposed relationship is applied to study the elastic constants of the solids of significance to geophysics applications. The calculated values of

2003-12-1 Knowledge of the elastic properties of all candidate mantle minerals and how these properties vary with temperature and pressure is required to accurately describe the composition and structure of Earth's upper and lower mantle. It is generally believed that the four dominant minerals of Earth's upper mantle are olivine, orthopyroxene, clinopyroxene, and pyrope garnet, even though

1989-6-1 The main purpose of this paper is to describe in some detail an experiment which allows the measurement of elastic constants of mantle minerals into the temperature range exceeding T θ = 1.5, where θ is the Debye temperature.We need these experimental data to establish firmly the thermodynamic and mechanical behavior of solids well into the classical range of T, which is of
