At the yield point
(strain = 4%), the scattering intensity on the equatorial direction begin to decrease, resulting in four scattering peaks distributing in each quadrant.
This explains why engineers who are used to working with metals are surprised that plastic materials cannot operate as close to their yield point
as metals can.
, represented by georeferenced bags, presented a low spatial dependency, because semi-variance did not increase significantly together with the distance among the pairs of points analyzed (Figure 2), resulting in 69% randomness among points (Table 3).
This selects all of the yield points
within this area.
In general, semicrystalline polymers with a lamellar morphology have well-defined yield points
And it becomes easier again while you make the transfer to manufacturing, especially if you're struggling to increase your yield points
," Liehr says.
Furthermore, in the true stress-true strain response two yield points
can be distinguished: one at smaller strains ([approximately equal to] 0.
For example, if we wanted to check on the possible correlation between yield and phosphorus (P), we would need a data set of yield points
from a yield monitor that has an associated P.
can be determined with creep/recovery tests or with controlled ramps.
can be determined with creep/ recovery tests or with stress-controlled ramps.
Upper and lower yield points
, which cause stick-slip friction, are commonly observed," he says.
The B values in films Bl tested before the yield points
increased with the progressing relaxation in contrast to other groups of films with constant or decreasing values of parameter B (see Table 7).
