Rate-independent systems

A Mielke, T Roubíček - Applied Mathematical Sciences, 2015 - Springer
Our work on rate-independent systems was stimulated by our search for evolutionary
material models for shape-memory alloys that are flexible enough to encompass nonlinear …

Delamination and adhesive contact models and their mathematical analysis and numerical treatment

T Roubíček, M Kružík, J Zeman - Mathematical methods and models …, 2014 - World Scientific
This chapter reviews mathematical approaches to inelastic processes on the surfaces of
elastic bodies. We mostly consider a quasistatic and rateindependent evolution at small …

BV solutions and viscosity approximations of rate-independent systems∗

A Mielke, R Rossi, G Savaré - ESAIM: Control, Optimisation and …, 2012 - cambridge.org
In the nonconvex case, solutions of rate-independent systems may develop jumps as a
function of time. To model such jumps, we adopt the philosophy that rate-independence …

Damage of nonlinearly elastic materials at small strain–Existence and regularity results–

M Thomas, A Mielke - ZAMM‐Journal of Applied Mathematics …, 2010 - Wiley Online Library
This paper discusses an existence result for energetic solutions of rate‐independent
damage processes and the temporal regularity of the solution. The authors consider a body …

Multiphase field modeling of grain boundary migration mediated by emergent disconnections

M Gokuli, B Runnels - Acta Materialia, 2021 - Elsevier
Abstract Knowledge about grain boundary migration is a prerequisite for understanding and
ultimately modulating the properties of polycrystalline materials. Evidence from experiments …

Thermodynamics of rate-independent processes in viscous solids at small strains

T Roubíček - SIAM Journal on Mathematical Analysis, 2010 - SIAM
So-called generalized standard solids (of the Halphen–Nguyen type) involving also
activated rate-independent processes such as plasticity, damage, or phase transformations …

Convergence of alternate minimization schemes for phase-field fracture and damage

D Knees, M Negri - Mathematical Models and Methods in Applied …, 2017 - World Scientific
We consider time-discrete evolutions for a phase-field model (for fracture and damage)
obtained by alternate minimization schemes. First, we characterize their time-continuous …

Complete damage in elastic and viscoelastic media and its energetics

A Mielke, T Roubíček, J Zeman - Computer Methods in Applied Mechanics …, 2010 - Elsevier
A model for the evolution of damage that allows for complete disintegration is addressed.
Small strains and a linear response function are assumed. The “flow rule” for the damage …

Adhesive contact of visco-elastic bodies and defect measures arising by vanishing viscosity

T Roubicek - SIAM Journal on Mathematical Analysis, 2013 - SIAM
An adhesive unilateral contact of elastic bodies with a small viscosity in the linear Kelvin--
Voigt rheology at small strains is scrutinized. The flow rule for debonding the adhesive is …

Energetic versus maximally-dissipative local solutions of a quasi-static rate-independent mixed-mode delamination model

R Vodička, V Mantič, T Roubíček - Meccanica, 2014 - Springer
