Hi Sandeep, Peter,


Looking at this and the other discussion with adhk, I wanted to add something that might be relevant:


you can perform a full harmonic analysis on viscoelastic materials by defining frequency dependent elastic modulus, Poisson's ratio and damping using TB,ELASTIC and TB,DAMP commands (WB does not support this in GUI, so you'll need to use command snippets). It still assumes linear response so large-deformation effects are not included.
