The special phase morphology and the resulting physical proper ties of the final product are said to be decisively determined by the selected screw configuration, as well as by the shear and yield stress
to which the material is subjected.
They concluded that yield stress
and coefficient of adhesive friction are the two most important parameters that can significantly influence the scratch depth of a polymer.
During exploitation yield stress
increased 30%, limitary plasticity and impact bending and impact tension toughness decreased by 21% and 40% respectively .
Both initial yield stress
and initial flow coefficient increased with increasing oil content.
The elastic bending modulus and yield stress
were measured using a bending tester (Imoto Factory Co.
The R/S Plus rheometer with a higher resolution position encoder is said to provide improved yield stress
and creep measurement capability.
Cornell University scientists wanted to determine the effects of concentrations of xanthan gum and three starches on rheological characteristics: the flow behavior and vane yield stress
of certain mixtures.
2%) was described by yield stress
SY (MPa) and yield strain values.
Using the concentric cylinder geometry, researchers found the following parameters at 25 C: instantaneous yield stress
, ty0 (Pa)=41.
All CNT/PU films showed higher tensile modulus, yield stress
and fracture stress than neat PU, and these parameters increased as the nanotube concentration increased.
The yield stress
of a material is usually defined as the maximum stress, below which no flow will occur.
Using concentric cylinder geometry, these parameters at 25 C were: instantaneous yield stress
, tyy0 (Pa)=41.
