Although it is known that the stress field in dissimilar materials under specified surface tractions generally depends on three independent elastic parameters, what three concrete parameters are useful and effective has yet to be studied. The authors showed previously that the axisymmetric problem is a special case of 3-dimensional problem of which the stress field depends on three elastic parameters and (α, β, γ) (α, β : Dundur's parameter, γ : product of two Poisson's ratios) is a useful combination of elastic parameters to deal with the problem, and proposed to use (α, β, γ)as parameters also for general 3-dimensional problem. In this paper, the fundamental properties of (α, β, γ) are studied and it is shown that these parameters exist in the closed domain in the 3-dimensional space of (α, β, γ).
