Hello,
I am trying to account for amplitude damping of acoustic vibration of a polymer disc, using Ansys software. I am currently using Harmonic Acoustics module in Ansys, which seems to be the only one allowing FSI boundary between the surrounding acoustic medium (water) and the structure (polymer disc).
I recently asked Ansys support, and turns out the effect of damping on amplitude of vibration cannot be modeled with it: https://forum.ansys.com/discussion/comment/125750#Comment_125750
Now my question is, is there any way to work around this issue by changing the mechanical properties of the polymer in my mode, to account for viscous damping of water? Like probably to calculate some kind of equivalent damping to assign to polymer material in my model instead?
Thanks in advance for your help.
Parinaz Sadri-Moshkenani You would need to know the correct damping in order to make a 'hack' like that, so that you can fit your structural mechanics model. Or switch to COMSOL Multiphysics.
