Modeling finite viscoelasticity based on the Green-Naghdi kinematic assumption and generalized strains
Ju Liu, Chongran Zhao, Jiashen Guan
We propose a modeling framework for finite viscoelasticity, inspired by the kinematic assumption made by Green and Naghdi in plasticity. This approach fundamentally differs from th…
A continuum and computational framework for viscoelastodynamics: III. A nonlinear theory
Ju Liu, Jiashen Guan, Chongran Zhao +1
We continue our investigation of viscoelasticity by extending the Holzapfel-Simo approach discussed in Part I to the fully nonlinear regime. By scrutinizing the relaxation property…
A continuum and computational framework for viscoelastodynamics: II. Strain-driven and energy-momentum consistent schemes
Ju Liu, Jiashen Guan
We continue our investigation of finite deformation linear viscoelastodynamics by focusing on constructing accurate and reliable numerical schemes. The concrete thermomechanical fo…
A structure-preserving integrator for incompressible finite elastodynamics based on a grad-div stabilized mixed formulation with particular emphasis on stretch-based material models
Jiashen Guan, Hongyan Yuan, Ju Liu
We present a structure-preserving scheme based on a recently-proposed mixed formulation for incompressible hyperelasticity formulated in principal stretches. Although there exist H…
