Takayanagi s model is a phenomenological model obtained by combination of serial and parallel models. The composite modulus ( c(T)) is determined by (17.4) with X, an adjustment parameter. 

A composite is described with the aid of the same Takayanagi s models which were discussed above. The equivalence of both the models enables them to be described with the aid of one equation. If viscoelastic Poisson s ratio (i = i i- ii ) is equal to v = v =p, then the dynamic shear modulus...
