Abstract : The vibrations of a concentrated mass suspended from a coiled spring are studied when the material of the spring is capable of deforming both elastically and in consequence of creep. When the creep law is linear, the attenuation of the vibrations is independent of the amplitude. When the creep law is non-linear in the sense that the creep rate is a power function of the force transmitted by the spring, with the exponent greater than unity, the attenuation increases with increasing amplitude.
