i am trying to model homogeneous linear viscoelastic model with the properties of cells ..and a polystyrene bead inside the viscoelastic material .my final result what i am expecting is to get the creep and stress relaxation behavior of the viscoelastic material .. now my problem is i have the poisson ratio of 0.499 and shear modulus of 0.026Pa at frequency 5Hz (i got this value from a friend who did phd in biological field ),i calculated young modulus E by using formula G=E/2(1+v) now how should i define it with respect to generalized maxwell model for which the linear viscoelastic material are designed in comsol4.3a . how will define the relaxation time and shear modulus in this case for this model ..please help me in this case ..
