However, the yield stresses were not the same with CW_MD having the highest yield stress of 1.8 MPa, both directions in EB had a yield stress of 1.2 MPa and the yield stress in CW_TD was 0.8 MPa.
The mechanism that how aggregates influence the yield stress of paste is studied in order to offer a reference for paste backfill technology.
Effect of Temperature on Regression Yield Stress. The aim of this section was to explain the mechanism how temperature affects the paste yield stress.
The variable response corresponds to the physical-mechanical property in the study: yield stress (maximum stress that can be caused the material with no deformation), elastic modulus (measure of the resistance to elastic deformation), thickness and tear resistance.
The trend of decrease in yield stress with increase in operating temperatures is almost similar to that of UTS.
Then, the fluid is constrained and cannot flow until the pressure difference between internal surface and external surface is higher than that produced by the yield stress of MRF.
MR fluids are characterized by an increase in dynamic yield stress upon application of a magnetic field.
On the other hand, rainfall-induced landslides occur when the excess load generated by water in saturated soil overcomes the yield stress of the soil.
Figure 1 contains the key points that we customarily obtain from the data sheet; the yield stress and strain as well as the modulus.
The RST Rheometers are unique because they operate in both controlled stress and controlled rate modes and can perform all of the following tests: viscoelastic modulus, yield stress, viscosity vs.
This model is more effective in the describing of a non-Newtonian blood flow because it contains two parameters such as the yield stress and the plasma viscosity but Casson model is considered only yield stress.
