Maxwell Material-Series Material

[nimatehran]

Hello,

1- Is ViscousDamper uniaxialMaterial different from defining Viscous uniaxialMaterial and stiffness material in series (Maxwell model)?

2- How can i get a proper number for the ($alpha : Viscous damper exponent) in the ""uniaxialMaterial ViscousDamper"" in my model?
