Generating Line Spectra from Experimental Responses. III. Interconversion between Relaxation and Retardation Behavior

Abstract

An algorithm is described which allows relaxation line spectra to be interconverted into retardation line spectra, and vice versa. The first line spectrum is generated from a given experimental response such as the relaxation modulus, the storage modulus, or the loss modulus, or from a response such as the creep compliance, storage compliance, or loss compliance. The interconversion algorithm is here applied to the standard linear solid and liquid models, and to a 32-line spectrum simulating the behavior of an entangled polymer. © 1992, Taylor & Francis Group, LLC.
