Study results show that the addition of fiber will increase both the elastic modulus and the yield stress significantly.
Essentially, magnetofluid or magnetic liquid is a kind of magnetorheological fluids (MRF), only its yield stress is lower than conventional magneto rheological fluid [5].
Yield stress produced by tension mode is greater by three to four times than shear yield stress, but lower than compressive stress under the same magnetic field strength [14].
Figure 1 contains the key points that we customarily obtain from the data sheet; the yield stress and strain as well as the modulus.
2013) investigated the effect of different mineral admixtures and superplasticizer on the rheological properties of cement grout and determined that metakaolin increased yield stress, plastic viscosity, cohesion plate, and flow time due to the higher surface area associated with an increase in the water demand.
However, these curves are plotted as cycles-to-failure as a function of a stress amplitude normalized with respect to the yield stress--and nowhere in the 200 pages is there mention of what that yield stress is.
The yield stress of the mixture not exposed to vibrations was determined using the value of a sinking standard cone (used for slump measurements) and the following equation (Skripkiunas 2007):
This redesign enhances ease of use while adding popular features, such as a 7-inch full color touch screen to display all test parameters along with measured values for yield stress, viscosity and temperature.
The scientists have investigated the effect of concentration on the yield stress and tensile modulus of the PP film.
