yield point

[′yēld ‚pȯint]
(mechanics)
The lowest stress at which strain increases without increase in stress.

yield point

The lowest stress in a material (less than the maximum attainable stress) at which the material begins to exhibit plastic properties; beyond this point an increase in strain occurs without an increase in stress.

yield point

yield point
A measure of the amount of stress needed to permanently deform a material. When a material is stressed beyond its yield point or elastic limit, it will not return to its original shape and size when the stress is removed. The yield point of a material is slightly higher than its elastic limit.

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.
Tensile testing was conducted on the polycarbonate material to characterize the mechanical properties, and determine the modulus, yield point, and the proportional limit (Figure 7).
The top row of images shows the low-strain behavior, primarily in the region of yield point elongation.
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.
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.
If you are looking at returns purely from the rental yield point of view (distinct from the appreciation of the capital value of the property), then the best properties for you to purchase will be low-cost apartments.
Dispers 685 is especially suitable for some organic pigments, such as yellow, red and blue and produces outstanding development of color strength, improved rheology, lower yield point and strong reduction of mill base viscosity allowing for high pigment loading.
A nonwoven web made up of the pressure sensitive adhesive fibers has a basis weight of about 55 gpsm and a maximum load of at least about 30 gpcm, which is at least about 150% of the load at yield point.
The stress-strain curves of the two populations clearly differed in their behavior beyond the yield point and were probably derived from two different layers within the egg sac.
Contouring algorithms assume that each yield point in a data set is free of measurement errors.
