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…
