Concurrent enforcement of polyconvexity and true-stress-true-strain monotonicity in incompressible isotropic hyperelasticity: application to neural network constitutive models
Maximilian P. Wollner, Dominik K. Klein, Herbert Baaser +2
The design of physics-augmented neural networks (PANNs) for the purposes of constitutive modeling has received considerable attention as of late for a variety of material behaviors…
Hyperelastic stability landscape: A check for HILL stability of isotropic, incompressible hyperelasticity depending on material parameters
Herbert Baaser
In this paper, we describe a uniform and standardized approach for analytically verifying the stability of isotropic, incompressible hyperelastic material models. Here, we address…
Again anti-plane shear
Jendrik Voss, Herbert Baaser, Robert J. Martin +1
We reconsider anti-plane shear deformations of the form based on prior work of Knowles and relate the existence of anti-plane shear deformations…
Inconsistency of uhyper and umat in Abaqus for compressible hyperelastic materials
Herbert Baaser, Robert J. Martin, Patrizio Neff
In this article, we revisited Bažant's comments on the implementation of hyperelastic material models in commercial finite element software. We would like to clarify that our asser…
A finite element implementation of the isotropic exponentiated Hencky-logarithmic model and simulation of the eversion of elastic tubes
Boumediene Nedjar, Herbert Baaser, Robert J. Martin +1
We investigate a finite element formulation of the exponentiated Hencky-logarithmic model whose strain energy function is given by \[ W_\mathrm{eH}(\boldsymbol{F}) = \dfracμ{k}\, e…
