Reply To: harmonic analysis – viscoelastic material

[benjamin.starling]

Hi Henrique,

The viscoelasticity can be turned off per analysis system with the command snippet shown below. If the material has multiple tables, be sure to issue the correct Label(s) on the TBDELE command. You can also modify the material per analysis be reissuing the TB and TBPT commands

Below is the comparison of the model with and without the visoelastic material table. First is phase angle of the response at a single location, the second is the amplitude. My model shows very little sensitivity to the visco material, but that is because my model was made up just to test implementation.

When I soften the visoelastic properties by a factor of 100 I get the following comparison.

If you are not getting the expected results, there is something else wrong with the model or material setup. Please upload an archived workbench project, and provide more information about the expected results, if you would like me to investigate further.
