Hello everyone,
Could anyone please tell me how to find damping ratio in ANSYS(I am using ANSYS 11.0).
I am trying to obtained FRF (freq vs displacement curve )with guessing constant damping 2% and then to find damping ratio by half-power or 3 dB method.
Is it correct way ??.why we have to...
Hello friends,
I have done modal analysis on a sandwich beam.Once I got natural frequencies I did harmonic analysis and obtained response curve (i.e amplitude vs. frequency) without initially considering any damping.Then,I used half-power method (or 3dB method)to find damping ratio.I run the...
