It is expected, therefore, that an evolution of an yield point
in epoxy glass aged under a postyield strain is different from that of epoxy glass aged under preyield strains.
The viscosity in Herschel-Bulkley is approximated as a constant value before the yield point
(while the actual viscosity is much lower), and its slope is discontinuous.
The increased time of zero-order approach may be due to the near zero slope of the stress-strain curve near the Yield point
Stress-strain curves for Thermolyn Rigid and Orfitrans Stiff exhibited maxima at the break point, comparatively low stress at the yield point
, and a relatively long strain elongation period before breaking.
Experimental results pertaining to yield point
and ultimate point are presented in Tables 3 and 4 respectively.
iii) During Luders-band propagation (lower yield point
) the AE level (energy) is lower than that at the upper yield point
Low ductility or brittle materials may not necessarily have well defined yield points
, but do exhibit definite failure points, since they fail in compression by a shattering type of fracture.
The 5 percent yield point
for the 2-inch tenons averaged 67.
The yield point
at 23[degrees]C (73[degrees]F) is found to be about:
Each yield point
would be divided by the area it represents and then multiplied by the price of the crop.
the tangent modulus at the yield point
, seem to be quite equal for both fiber populations.
Cosat explains the spring has passed its "first yield point
," the point at which it will not return to its original length.
