A Simple and Efficient Lagrange Multiplier Based Mixed Finite Element for Gradient Damage
Johannes Riesselmann, Daniel Balzani
A novel finite element formulation for gradient-regularized damage models is presented which allows for the robust, efficient, and mesh-independent simulation of damage phenomena i…
A new Method for the in vivo identification of material properties of the human eye. Feasibility analysis based on synthetic data
Stefan Muench, Mike Roellig, Daniel Balzani
This paper proposes a new method for in vivo and almost real-time identification of biomechanical properties of the human cornea based on non-contact tonometer data. Further goal i…
Efficient and robust numerical treatment of a gradient-enhanced damage model at large deformations
Philipp Junker, Johannes Riesselmann, Daniel Balzani
The modeling of damage processes in materials constitutes an ill-posed mathematical problem which manifests in mesh-dependent finite element results. The loss of ellipticity of the…
A General, Implicit, Large-Strain FE Framework for the Simulation of Dynamic Problems on Two Scales
Erik Tamsen, Daniel Balzani
In this paper we present a fully-coupled, two-scale homogenization method for dynamic loading in the spirit of FE methods. The framework considers the balance of linear momentu…
