2. Simple rheological models
The structural or hysteretic damping model [equation () ] does not always correspond to the actual behavior of materials, as η often depends on frequency and temperature η = η (ω, T ). What's more, it doesn't predict in particular the response to an impulse (which involves a wide range of frequencies). As a result, other models have been developed; they are made up of simple, well-known elements such as the spring and the viscous damper, which respectively give a force proportional to the strain and the strain rate (figures 4 a and...
