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…

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…
