In this paper we analyze an isothermal and isotropic model for viscoelastic media combining linearized perfect plasticity (allowing for concentration of plastic strain and development of shear bands) and damage effects in a dynamic setting. The interplay between the viscoelastic rheology with inertia, elasto-plasticity, and unidirectional rate-dependent incomplete damage affecting both the elastic and viscous response, as well as the plastic yield stress, is rigorously characterized by showing… Expand
A finite-strain model for incomplete damage in elastoplastic materials
A three-dimensional model capable of describing coupled damage and plastic effects in solids at finite strains and the constitutive model results from the balance of conservative and dissipative forces is addressed. Expand
Balanced Viscosity Solutions to a Rate-Independent Coupled Elasto-plastic Damage System
An additional approximation featuring vanishing plastic hardening is introduced in order to deal with the vanishing viscosity in the plastic variable in the rate-independent model coupling small strain associative elasto-plasticity and damage. Expand
Models of dynamic damage and phase-field fracture, and their various time discretisations
Several variants of models of damage in viscoelastic continua under small strains in the Kelvin-Voigt rheology are presented and analyzed by using the Galerkin method. The particular case, known as aExpand

Approximation of dynamic and quasi-static evolution problems in elasto-plasticity by cap models
This work is devoted to the analysis of elasto-plasticity models arising in soil mechanics. Contrary to the typical models mainly used for metals, it is required here to take into account plasticExpand
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 internal variable,Expand
Globally stable quasistatic evolution for strain gradient plasticity coupled with damage
We consider evolutions for a material model which couples scalar damage with strain gradient plasticity, in small strain assumptions. For strain gradient plasticity, we follow the Gurtin–AnandExpand
Perfect Plasticity with Damage and Healing at Small Strains, Its Modeling, Analysis, and Computer Implementation
The quasistatic, Prandtl-Reuss perfect plasticity at small strains is combined with a gradient, reversible (i.e. admitting healing) damage which influences both the elastic moduli and the yield stress to form a system of variational inequalities. Expand
Small-strain heterogeneous elastoplasticity revisited
The elastoplastic quasi-static evolution of a multiphase material—a material with a pointwise varying yield surface and elasticity tensor, together with interfaces between the phases—is revisited inExpand
Thermodynamics of Elastoplastic Porous Rocks at Large Strains Towards Earthquake Modeling
A mathematical model for an elastoplastic porous continuum subject to large strains in combination with reversible damage (aging), evolving porosity, water and heat transfer is advanced and existence of suitably defined weak solutions and a convergence result for Galerkin approximations is proved.

We consider the dynamic evolution of a linearly elastic-perfectly plastic thin plate subject to a purely vertical body load. As the thickness of the plate goes to zero, we prove that theExpand
