It's a linear dynamic analysis. So the same materials as you need for a linear analysis.
But you also need damping props. If you are using material damping you input with materials. Otherwise using the damping section to input the damping props.
I'm pretty sure these will do. It may force you to add some of the ones I've lined out, but I don't think they directly affect vibration simulation.
Compressive Strength in X
Thermal Expansion Coefficient
Material Damping Ratio
Pretty sure it will want poissons ratio. Material damping only if you are going to use composite damping. Not common in my experience.
If you do'nt use material damping, you will get infinite response at the natural frequency and you won't be able to integrate under the psd. The GRMS is pretty sensitive to the damping ratio you choose.
It may want poisson's ratio. In fact I had it in and then went back and edited the post. I just can't think of any use for it in the damped vibration model.
correct. but there is raleigh and modal damping that could be used. http://help.solidworks.com/2013/English/SolidWorks/cworks/c_Damping_Effects.htm?id=cd4a1c8b37bd472f963716ba4e21360a#Pg0
(unless they aren't available for random vibe, but i don't remember that being a limitation)
these are more common in my experience.
It does seem to want poisson's ration. I'm not sure why. I'll have to understand it a little better.
