Hi,

i am trying to model a viscoelastic material using the TB,prony option. In the ANSYS help manual, it says that you need to input

C1 Relative modulus
C2 Relative time

can someone tell me what these constants represent?

thanks

Hi
i think C1 and C2 are WLF constants which are use ful for thermoreheological assumption

Dear all,

if you can download this paper "Finite element analysis of low temperature thermal nanoimprint lithography
using a viscoelastic model" most of you will get answers about prony model constant..
Hope it will help you
