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…
