One of the simplest is the Tresca criterion, which evaluates normal stresses and shear stresses (Fenske et al.
The modified Tresca criterion is one of the early criteria proposed to describe the yielding of polymers.
On the contrary, modified Tresca criterion gives better prediction of the yield locus of the annealed PP-based polymers (PPH-160, PP/10POE-160).
As for the parameters of the modified Tresca criterion ([tau].
10 the relevant envelope of the modified Tresca criterion of the PPH-160 is constructed using Eq.
