dynamic analysis

[gcm981]

Hello, guys.

Just one question. having a circular plate and wanting to calculate the stresses on it to vary the accelerations imposed on the constraints to a certain frequency what type of analysis should I carry out?

Thank you very much to all of you.

an analysis of the problem.. .
Do you need fatigue? a bump? maximum voltage?

in the latter case, it is easier to apply a distributed force on the plate, of entity equal to the density of the plate for maximum acceleration.

Thank you very much for the tip.

Exactly, I care to calculate the maximum voltage inside the plate.

I just have a doubt. By multiplying the density for the allergy we no longer have a force or a pressure. . .

Moreover as we approach the proper frequency of the system should increase stress just as we are close to the resonance of the system, how to simulate this behavior?

I hope I've been clear.

thank you again

if the supports have a cyclical shift near the resonance of the plate (which I imagine is quite high, even if I don't have the data, I say, in the field of the auditable) then you have to do a dynamic analysis. I have no idea how to deal with it, but I'm sure it's not a "just the data, I'm cutting them and I get the result."

If you are far from the resonance...for density of course I mean a surface density, then kg/m2 of the plate, which for an acceleration (m/s2) does just a pressure (n/m2)
