Abstract： The behavior of elastic modulus related with strain amplitude is studied. It was found that modulus behaves softening when internal friction exhibits normal amplitude-dependent effects, while increases slightly with the appearance of anomalously amplitude-dependent effect. With the decrease of frequency of measurement, the variation of modulus with amplitude becomes small. A trial for obtaining information from amplitude internal friction peak was made on the basis of Debye equations.
