tension] represent the compressive and tensile

yield stresses or flow stresses at the given compressive and tensile plastic strains, respectively.

Although none of the comparative studies [9, 16, 50] reported

yield stresses or yield strains, the load-extension data were presented graphically in comparative studies I [9] and III [16].

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.

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.

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.

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

yield stresses assumed [[sigma].

Unfortunately, accurate measurements of

yield stresses and degrees of thixotropy are difficult and shear histories and other variables impact results.

The engineering stresses, corresponding to that strain at yield, are combined with the engineering

yield stresses from the tensile experiments in Fig.

as well as high polydispersity in size and shape may be at the origin of strong fiber--fiber interactions responsible for the high

yield stresses observed.

The comparisons between the predicted

yield stresses and experimental data versus the rubber and talc volume contents at a strain rate of [10.
