摘要:
While the concept of the complex modulus is based on a forced vibration experiment it is a frequent practice to perform instead a much simpler free damped oscillation test from which an approximate value of the modulus is then evaluated. The validity of this approach and the ensuing errors are discussed and illustrated on a multielement generalized Maxwell body. It is shown that with modifications the method is applicable even for highly damped materials.
