The objective of this work is to present the numerical implementation for the alternative determination of vis-coelastic material properties without using Poisson’s ratios as presented in [1]–[3]. The presented method is based on the 3-D generalized constitutive relations viscoelastic materials with hereditary integrals. The numerical procedures are based on experiments using photogrammetric and tensile testing instrumentation, which provide stress data in the 1-D loaded direction and strains in both longitudinal (loaded) and transverse directions. Measurements and data analyses include both starting transient and steady-state loading conditions. The paper presents the implementation of solutions for the linear case, where the relaxation time values are prescribed according to to the scheme presented in [1] and [3]. Convergence of the Prony series representations is evaluated. [ABSTRACT FROM AUTHOR]
