relaxation and retardation





the term "relaxation time" has been described. it is used in combination with tests presetting the strain (deformation) or strain rate (shear rate), eg, when performing relaxation tests. on the other hand, the term "retardation time" is used for tests when presetting the stress, eg, when performing creep tests.

this paper presents a simple and practical approach to obtain the continuous relaxation and retardation spectra of asphalt concrete directly from the complex (dynamic) modulus test data. the spectra thus obtained are continuous functions of relaxation and retardation time. preliminary examination of an approach to relaxation and retardation in viscoelasticity. relaxation and retardation can be asymptotically equivalent for small deborah number. causal relaxation is shown to correspond to illposed retardation through this equivalence.
