A computational framework for pharmaco-mechanical interactions in arterial walls using parallel monolithic domain decomposition methods
Daniel Balzani, Alexander Heinlein, Axel Klawonn +5
A computational framework is presented to numerically simulate the effects of antihypertensive drugs, in particular calcium channel blockers, on the mechanical response of arterial…
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…
Multidimensional rank-one convexification of incremental damage models at finite strains
Daniel Balzani, Maximilian Köhler, Timo Neumeier +2
This paper presents computationally feasible rank-one relaxation algorithms for the efficient simulation of a time-incremental damage model with nonconvex incremental stress potent…
Evolving Microstructures in Relaxed Continuum Damage Mechanics for Strain Softening
Maximilian Köhler, Daniel Balzani
A new relaxation approach is proposed which allows for the description of stress- and strain-softening at finite strains. The model is based on the construction of a convex hull re…
Simulation of crack propagation through voxel-based, heterogeneous structures based on eigenerosion and finite cells
Dennis Wingender, Daniel Balzani
This paper presents an algorithm for the efficient simulation of ductile crack propagation through heterogeneous structures, as e.g. metallic microstructures, which are given as vo…
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…
An extended Hamilton principle as unifying theory for coupled problems and dissipative microstructure evolution
Philipp Junker, Daniel Balzani
An established strategy for material modeling is provided by energy-based principles such that evolution equations in terms of ordinary differential equations can be derived. Howev…
