Viscoelastic material in Ansys 2

[sym]

I have to use visco88 element, but I have no idea how to define constants (from C1 to C95). Can anyone give me some hints ?

Thanks!

The best way to define c1~c95 is using material test data,
such as uniaxial,shear...etc.

i think some of the constants have not to be defined.

Does any one else could be more specific in answering SYM's question? I am very keen in knowing more about this too.
By the way, SHANQIU, I don't know if your link is correct. I did not manage to access it.
