and castor oil derivatives that form physical networks, which produce

yield stresses.

Figure 3 shows that the replacement of 10% of Portland cement (by weight) with opoka and dolomite dust additives (Compositions III and VI) reduce the

yield stresses of cement pastes by 9.

Higher fiber concentrations lead to a dominant elastic behavior and higher

yield stresses.

A generally anisotropic hardening model for big offset-strain

yield stresses, Acta Mech.

But the change of values for elongation and reduction of area measured at different coefficients of friction is even smaller (less than 5%) than the change of tensile and

yield stresses.

The maximum shrinkage stress values from drying were similar to those of relaxed compression

yield stresses at the same temperature and RH conditions.

1), there are six independent anisotropic coefficients in which F, G, H are anisotropic coefficients of the main

yield stresses and L, M, N are anisotropic coefficients of the shear

yield stresses in the principal axes of anisotropy.

e] (z) of the same column and the same forces N , F applied, but

yield stresses assumed [[sigma].

For all blends studied, the reported

yield stresses are lower than the yield stress of neat PP and the tensile strength of neat PS which are 31.

Values of yield criteria parameters obtained by fitting all available

yield stresses.

Yield stresses in the case of T = 175[degrees]C and W = 1.
