An enhanced single Gaussian point continuum finite element formulation using automatic differentiation
Njomza Pacolli, Ahmad Awad, Jannick Kehls +4
This contribution presents an improved low-order 3D finite element formulation with hourglass stabilization using automatic differentiation (AD). Here, the former Q1STc formulation…
Automated Model Discovery for Tensional Homeostasis: Constitutive Machine Learning in Growth and Remodeling
Hagen Holthusen, Tim Brepols, Kevin Linka +1
Soft biological tissues exhibit a tendency to maintain a preferred state of tensile stress, known as tensional homeostasis, which is restored even after external mechanical stimuli…
An anisotropic, brittle damage model for finite strains with a generic damage tensor regularization
Tim van der Velden, Stefanie Reese, Hagen Holthusen +1
This paper establishes a universal framework for the nonlocal modeling of anisotropic damage at finite strains. By the combination of two recent works, the new framework allows for…
Accounting for plasticity: An extension of inelastic Constitutive Artificial Neural Networks
Birte Boes, Jaan-Willem Simon, Hagen Holthusen
In this work, we extend the existing framework of inelastic constitutive artificial neural networks (iCANNs) by incorporating plasticity to increase their applicability to model mo…
