Abstract:

A formulation of the temperature independent Gruneisen parameter gamma is presented in terms of the lattice parameters a, b, and c of a monatomic cubic crystal. The formulation includes the effects of Poissons ratio, sigma, and the modified Cauchy relation. The modification of gamma introduced by these latter quantities is seen to be significant. In particular, a correction generated by consideration of the variation of sigma with volume is shown to account for differences between the Slater and Dugdale-MacDonald formulae for gamma. Author
