A vanishing viscosity approach to a rate-independent damage model
D Knees, R Rossi, C Zanini - Mathematical Models and Methods in …, 2013 - World Scientific
We analyze a rate-independent model for damage evolution in elastic bodies. The central
quantities are a stored energy functional and a dissipation functional, which is assumed to …

Damage and fracture evolution in brittle materials by shape optimization methods
This paper is devoted to a numerical implementation of the Francfort–Marigo model of
damage evolution in brittle materials. This quasi-static model is based, at each time step, on …

Differential, energetic, and metric formulations for rate-independent processes
In these notes we want to give an overview of the recently developed theory for rate-
independent systems. Such systems are used to model hysteresis, dry friction …

A phase-field damage model based on evolving microstructure
H Hanke, D Knees - Asymptotic Analysis, 2017 - content.iospress.com
In this paper we discuss a damage model that is based on microstructure evolution. In the
context of evolutionary Γ-convergence we derive a corresponding effective macroscopic …

From discrete visco-elasticity to continuum rate-independent plasticity: rigorous results
We show that continuum models for ideal plasticity can be obtained as a rigorous
mathematical limit starting from a discrete microscopic model describing a visco-elastic …

A quasilinear differential inclusion for viscous and rate-independent damage systems in non-smooth domains
D Knees, R Rossi, C Zanini - Nonlinear Analysis: Real World Applications, 2015 - Elsevier
This paper focuses on (incomplete) rate-independent damage in elastic bodies. Since the
driving energy is nonconvex, solutions may have jumps as a function of time, and in this …

Rate-independent damage in thermo-viscoelastic materials with inertia
We present a model for rate-independent, unidirectional, partial damage in visco-elastic
materials with inertia and thermal effects. The damage process is modeled by means of an …

Concentration versus oscillation effects in brittle damage
This work is concerned with an asymptotic analysis, in the sense of Γ‐convergence, of a
sequence of variational models of brittle damage in the context of linearized elasticity. The …

A temperature-dependent phase-field model for phase separation and damage
In this paper we study a model for phase separation and damage in thermoviscoelastic
materials. The main novelty of the paper consists in the fact that, in contrast with previous …
