title = "Analytical, experimental and computational viscoelastic material characterizations absent Poisson's ratios",
abstract = "The objective is to formulate numerical implementations of analytical and experimental protocols to determine linear viscoelastic material properties without using Poisson's ratios, as devised in [1 - 3]. The presented analysis is in terms of 3-D generalized viscoelastic constitutive relations with hereditary integrals and relaxation moduli or creep compliances. The numerical procedures are based on experimental data from photogrammetric and tensile testing instrumentations, which provide stress data in the 1-D loaded direction and strains in both longitudinal and transverse directions. Measurements and data analyses include the entire time range of starting transient and steady-state loading conditions. The paper presents implementations of solutions for the linear case, where the relaxation time values are prescribed according to schemes of [1 - 3]. Convergence of the Prony series representations is evaluated. The full nonlinear determination of the relaxation times is also derived. Analytical simulations of experiments are formulated and evaluated to determine the accuracy of fit of the new protocol and and to evaluate experimental data.",
