yield point

n
(General Physics) the stress at which an elastic material under increasing stress ceases to behave elastically; under conditions of tensile strength the elongation is no longer proportional to the increase in stress. Also called: yield stress or yield strength

Since molecular structure in the interphase is not as well ordered as that in the crystalline lamella, structure of the former may be affected by deformation at a strain level below the yield point, which provides a reasonable explanation for the observed decrease of the tangent modulus in the second test by introducing deformation in the first test at the strain level below the yield point.
This curve stops just beyond the yield point so that the details contained in the initial stages of the test can be easily viewed.
Because the stress level is below the yield point of the material, molecular reorganization takes place exclusively through disentanglement, as there is no opportunity for yielding.
The yield strengths of the UNS S17400 stainless steel are much lower, and the material exhibits extensive yield point elongation absent in 17-4PH stainless steel.
If such hand-type deformation were possible then most of our bridges, metal supports, and buildings would be in grave danger of collapse, since the yield point becomes extremely and miraculously low when brought to the hand of talented performers such as Mr.
Safe pipe tripping speeds are affected by mud rheological properties such as mud plastic viscosity and yield point.
Neat PEEK shows a typical polymer yield point as compared to its composites, followed by a softening range, and a roughly straight sub domain up to 0.
3] were showed linear behavior upto yield point and then seem to behave in a plastic fashion is shown in fig.
Yield Point--In a mechanical sense, the yield point is the point where structural changes begin.
Purpose of the tests was to obtain information concerning ultimate moment capacity, capacity at a "5%" yield point, and semirigid behavior of the joints.
