Hi, I am looking for the relation between the stiffness, the young's modulus and the loss factor. I think that's K = E(1+i*η), but I'm not sure of that. Can someone confirm that equation ? Because I need to justify the following equation : η = imaginary(K) / real(K). Thanks a lot, B.D

Hi Anyone can help me ? Thanks B.D

Hi everyone, I'm french, so sorry for my bad english. I have a problem to compute the damping as a function of frequency. In fact, I plot the transfer function between the input (which is a force applied bu a hammer) and the output (which is an acceleration). Therefore, I can analyse the mode...
