Material Library Manager: damping value - where is this used?

When I select a material in the Material Library Manager, "damping" is one of the available entries under General Properties. For what type of analysis would the material's damping be used?

 

Thanks,

Don C.

Hi Don,

 

This is material damping used in MES analyses.  Typically, this value is left as zero, unless physical testing has been performed to determine this value, then it is still very small, such as ~"0.05".  I think this correlates to "Tangential damping" is described in research articles I have previously read.

 

Just confirmation that it is best to leave as zero unless you know otherwise :-)
