DESCRIPTION:Speaker: Alexei Gazca\nhosted by Julian Fischer\, Erika Maringo
va\nAbstract: In this talk\, I will introduce some aspects of the mathemat
ical modelling of inelastic solids\, placing particular emphasis on models
that are compatible with the second law of thermodynamics. In particular\
, I will describe a recent model from [Cichra\, Prša\; 2020] and discuss
its numerical approximation via the finite element method. One of the adva
ntages of the approach considered here is that it is not necessary to intr
oduce additional concepts\, such as the plastic strain. Moreover\, as a co
nsequence of the thermodynamically consistent derivation\, one is able to
compute the evolution of the temperature field without additional complica
tion. I will also showcase an application of this modelling approach to th
e Mullins effect\, for which up to date there had been no simple yet fully
coupled thermo-mechanical model. This is joint work with David Cichra\, V
ít Prša and Karel Tma.
