how to include damping in a shock study
how to include damping in a shock study
(OP)
Hi All,
I need to perform a shock study that included damping. From all my research, a Response Spectrum Analysis is the study used for shock. I don't see where damping can be included in this study.
Is there another study I can use for shock that would include damping. My customer has given me a Shock Response Spectra (Freq versus peak acceleration) and a damping value.
Thanks for your input.

I think I forgot about this because not all my materials have a damping factor specified in the material properties and wanted to globally set it like I did in my random study. It won't be too hard to go in and artificially set them all to 5% which the customer wants.
Thanks for the quick response. My Monday will be much smoother now.

You need to read this article of mr. Irvine:

You also can use transient analysis for shock.

In this book also explayning responce spectrum analysis for shock. The problem is precisely in getting the load. To do this, you need to use another application.
