Description	This contribution examines the capabilities of three differential constitutive models (XPP, PTT-XPP, and modified Leonov) in predicting rheological properties of two virtually linear polyethylene materials (HDPE Tipelin FS 450-26, mLLDPE Exact 0201) with specific attention to both steady as well as transient shear and uniaxial elongational flow situations. For each situation the (dis)advantages of the individual models are discussed and both, qualitative and quantitative model efficiency evaluation has been carried out.

(en) Příspěvek se zabývá predikčními možnostmi tří vybraných konstitučních modelů, a to s ohledem na reometrické vlastnosti dvou lineárních polyetylénových materiálů (HDPE Tipelin FS 450-26, mLLDPE Exact 0201). Pozornost byla věnována ustáleným i transientním smykovým a elongačním tokovým situacím. Byly ukázány kvalitativní i kvantitativní přednosti či zápory jednotlivých modelů. (cs)
