yield strength

The load on a material that causes the initial indication of permanent distortion. It is the stress point at which a material exhibits a specified deviation from the proportionality of the stress and strain. See yield point.

At the two-week checkpoint, both yield strength and elastic modulus for all three groups of PDO increased and reached similar levels regardless of initial PDO annealing conditions.
Consequently, its yield strength was calculated using the 0.2% offset method used for defining the yield strength of typical high-strength steel.
The FSP inserts slow the projectile and absorb more of its kinetic energy due to the insert's increased yield strength.
Yield strength follows the same trend that of the UTS, while the maximum yield is observed for A-7.The plates welded with 710 rpm TRS showed the highest elongation for all the three D/d ratios.
One of the objectives of this investigation was the assessment of the experimental equivalent strain rate of Charpy tests for several steels, by comparing the results of dynamic tensile tests conducted at different strain rates and the estimates of dynamic yield strength obtained from instrumented Charpy tests by means of Eqs.
The increase of yield strength can be due to precipitation strengthening mechanism, mostly because of niobium carbide (NbC) particles or free nitrogen contained in the steel.
The biggest crack depth [t.sub.c] of the corrosion fracture high-strength bolt decreases with the increase of material yield strength [[sigma].sub.s] and applied stress [sigma], in which material yield strength [[sigma].sub.s] had significant effect on crack depth [t.sub.c].
Also, it can be observed that the low yield strength steel may reduce deformation.
It is probably the most simple and direct method of measuring unconfined yield strength, a parameter related to cohesivity.
An effect of lowered and elevated temperature on ultimate tensile strength and 0.2 percent offset yield strength for both steels using marked points is presented in Fig.
