Entropy-energy solutions for Thermo-Visco-Elastic systems with Mróz-type inelastic behavior
Tomasz Cieślak, Sebastian Owczarek, Karolina Wielgos
In this article, we study a thermodynamically consistent thermo-visco-elastic model describing the balance of internal energy in a heat-conducting inelastic body. In the considered…
Global regularity for a physically nonlinear version of the relaxed micromorphic model on Lipschitz domains
Dorothee Knees, Sebastian Owczarek, Patrizio Neff
In this paper, we investigate the global higher regularity properties of weak solutions for a linear elliptic system coupled with a nonlinear Maxwell-type system defined on Lipschi…

Dorothee Knees, Sebastian Owczarek, Patrizio Neff
We derive a global higher regularity result for weak solutions of the linear relaxed micromorphic model on smooth domains. The governing equations consist of a linear elliptic syst…

Dorothee Knees, Sebastian Owczarek, Patrizio Neff
In this paper we study local higher regularity properties of a linear elliptic system that is coupled with a system of Maxwell-type. The regularity result is proved by means of a m…
A Norton-Hoff model with an elastic and inelastic constitutive relationships dependent on temperature
Sebastian Owczarek
The aim of this paper is to prove the existence of weak solution for a quasi-static evolution of thermo-visco-elastic model with Norton-Hoff law of plasticity. The dependence on te…
A note on local higher regularity in the dynamic linear relaxed micromorphic model
Sebastian Owczarek, Ionel-Dumitrel Ghiba, Patrizio Neff
We consider the regularity question of solutions for the dynamic initial-boundary value problem for the linear relaxed micromorphic model. This generalized continuum model couples…

In this paper we use a property of the extension operator from the space of tangential traces of in the context of the linear relaxed micromorphic model, a…
Nonstandard micro-inertia terms in the relaxed micromorphic model: well-posedness for dynamics
Sebastian Owczarek, Ionel-Dumitrel Ghiba, Marco-Valerio d'Agostino +1
We study the existence of solutions arising from the modelling of elastic materials using generalized theories of continua. In view of some evidence from physics of meta-materials…

Leszek Bartczak, Sebastian Owczarek
We consider the quasi-static evolution of the thermo-plasticity model in which the evolution equation law for the inelastic strain is given by the Prandtl-Reuss flow rule. The ther…
Renormalised solutions in thermo-visco-plasticity for a Norton-Hoff type model. Part I: the truncated case
Krzysztof Chełmiński, Sebastian Owczarek
We prove existence of global in time strong solutions to the truncated thermo- visco-plasticity with an inelastic constitutive function of Norton-Hoff type. This result is a starti…
Existence of solution for a nonlinear model of thermo-visco-plasticity
Leszek Bartczak, Sebastian Owczarek
We study a thermodynamically consistent model describing phenomena in a visco-plastic metal subjected to temperature changes. We complete the model with the mixed boundary conditio…
A first regularity result for the Armstrong-Frederick cyclic hardening plasticity model with Cosserat effects
Krzysztof Chełmiński, Patrizio Neff, Sebastian Owczarek
The purpose of this article is to prove the Hölder continuity up to the boundary of the displacement vector and the microrotation matrix for the quasistatic, rate-independent Armst…

Krzysztof Chelminski, Patrizio Neff, Sebastian Owczarek
We propose an extension of the cyclic hardening plasticity model formulated by Armstrong and Frederick which includes micropolar effects. Our micropolar extension establishes coerc…
