Experimental Characterization and Finite Element Implementation of Soft Tissue Nonlinear Viscoelasticity

Abstract: Finite element (FE) models of articular joint structures do not typically implement the fully nonlinear viscoelastic behavior of the soft connective tissue components. Instead, contemporary whole joint FE models usually represent the transient soft tissue behavior with significantly simplified formulations that are computationally tractable. The resultant fidelity of these models is greatly compromised with respect to predictions under temporally varying static and dynamic loading regimes. In addition, models … Show more

“…A comprehensive study has been published by Yamamoto on different rheological soft tissue models by carrying out point-to-point palpation [16]. A nonlinear viscoelastic model was introduced by Troyer et al, which could be implemented in finite element modeling algorithms, creating a rheological-based hybrid soft tissue model [17]. A complex model of porcine liver has been introduced by Leong et al in [18], which was improved and validated in [2] and [19].…”

“…representation to develop a novel formulation, which can include nonlinear viscoelastic behaviour and model physiologically static and dynamic loading regimes [55]. A novel constitutive model formulated within the nonlinear integral representation of transversely isotropic tendon was also found to capture the nonlinear relaxation response of rat tail tendon fascicles [72,73].…”

“…Based on time-and strain-dependent mechanics of soft tissues, the QLV model separates tissue mechanical properties into a time-independent stress component and a time-varying relaxation function [49][50][51][52]. Owing to its reduced mathematical interpretation relative to more complicated nonlinear formulations, this theory has been widely applied to cartilage, ligament and tendon [50,[53][54][55]. However, because the QLV theory is developed on the assumption of an instantaneous step increase in strain and hold, the application of the OLV theory to more complicated in vivo loading patterns is limited and fits to experimental data can be limited by issues with convergence and non-unique solutions [56].…”

“…An advanced tissue model was proposed in [14] for the identification of soft tissue parameters, which were obtained from experimental data through curve fitting, however, valid results were not achieved. A nonlinear viscoelastic model was proposed by Troyer et al [15], which was intended for use in hybrid tissue models. However, none of these tissue models were fit to the representation of tissue behavior for both constant compression rate deformation and stress relaxation phases.…”
