Hello there, I was wondering if you could help me clarify the material damping in Abaqus. A lot of models in the literature state their “material loss factor” in their respective FEA software. Is this the same as the material structural damping in Abaqus?

I’m asking this because I tried to replicate a simulation and was off by about 100 Hz in the low frequency region (which is about 500 Hz in this case). However the error kept increasing such that I was off by 800Hz in the high frequency region (which is about 6000 Hz in this case). I have verified all parts of the numerical model but the damping seems unclear to me
