Abstract:

The new algorithm presented consists of the use of a ratio of factored polynomials in the reduced frequency to approximate the complex modulus and an artful procedure to evaluate the parameters. A corresponding Prony series is easily obtained to represent the relaxation modulus the creep compliance and discrete relaxation and retardation spectra are likewise easily obtained. Series representations with 50 terms are routinely used they are very convenient and well-behaved.
