Analysis of the relations for temperature dependence of elastic constants of solids

摘要

The relations, that have been developed based on three different assumptions of the isothermal Anderson-Gruneisen parameter and the method of generalization as suggested by Tallon [J. Phys. Chem. Solids 41, (1980) 837], for temperature dependence of elastic constants of solids are analysed in the paper. It is concluded that, as far as the goodness of fit is concerned, these relations are identical and further theoretical and experimental studies on the reasonableness of these assumptions are still necessary.
