The yield stress, 1.2 MPa, was the same in both directions but, a level of anisotropy was observed between the MD and the TD for larger strains.
There are many factors that can determine the yield stress. Many studies in last decades concentrate a lot on factors influencing yield stress for thickened or paste tailings.
Considering the abovementioned facts, the main objective of this research was to experimentally study the effect of temperature on apparent viscosity, shear stress, yield stress, and pipeline transport of paste.
The purpose of this paper is to evaluate the effect of the incorporation of additives on the mechanical properties of LLDPE films manufactured by extrusion blow formulated for use as covers in growing houses, through the evaluation of tensile properties (modulus of elasticity, yield stress) and tear resistance of the films.
where is the deviatoric stress tensor and [[sigma].sub.0] represents the yield stress or flow stress.
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].
Therefore, we should not expect to be able to use the material above the yield stress for even a very short duration.
Tables organize the data on each specific commercial product, listing tensile modulus, yield stress, yield at strain, stress at break, charpy notched impact, relative permittivity, dissipation factor, and water absorption.
Rheo3000 V.2 can perform a wide variety of tests, including viscoelastic modulus, yield stress, viscosity vs.
