First, the local fields of internal variables are decomposed on a reduced basis of modes. Second, the dissipation potential of the phases is replaced by its tangent second-order (TSO) expansion. The reduced evolution equations of the model can be entirely expressed in terms of quantities which are pre-computed once for all. 000015483 540__ $$aText je chráněný podle autorského zákona č. 121/2000 Sb. 000015483 653__ $$a 000015483 7112_ $$a24th International Congress of Theoretical and Applied Mechanics$$cMontreal (CA)$$d2016-08-21 / 2016-08-26$$gICTAM2016 000015483 720__ $$aSuquet, Pierre 000015483 8560_ $$ffischerc@itam.cas.cz 000015483 8564_ $$s157161$$uhttps://invenio.itam.cas.cz/record/15483/files/TS.SM15-4.01.pdf$$yOriginal version of the author's contribution as presented on CD, page 2887, code TS.SM15-4.01 . 000015483 962__ $$r13812 000015483 980__ $$aPAPER
