Water molecules diffused into PDO and acted as plasticizer to reduce the yield strength
, soften the modulus, and extend the elongation at break.
By contrast, the tensile strength and yield strength
both could meet the requirements when the content of Al is from 0.016 wt.% to 0.027 wt.%.
Two types of steel that differed in yield strength
, SM490 and HSB800, were used to evaluate the effect of enhanced yield strength
on the compressive strength development.
The higher yield strength
of AL7075 does stop the projectile completely compared to AL5182.
Based on the experimentation, effect of (D/d) ratio, welding speed and TRS on the UTS, yield strength
, % elongation are deduced and plotted.
where: [[sigma].sub.YS] = quasi-static yield strength
at the temperature of the fracture test, [t.sub.Q] = time to the onset of fracture instability or to the initiation of stable crack extension, and E = Young's modulus at the temperature of the fracture test.
However, this increase of yield strength
isn't sufficient enough and extrados location doesn't meet the minimum requirements.
If [t.sub.0] = 0.001 mm and [DELTA][sigma] = 100 Mpa, according to the formula (6) and (9), the relations of the material yield strength
, the applied stress, and the corrosion fracture fatigue life was obtained, as shown in Figure 6.
Also, it is also important to note that the equivalent plastic strain of bolted splices for the cases using the low yield strength
steel is much larger than that from A-SP case.
1988), [[rho].sub.s] and [f.sub.ys] are respectively the volumetric ratio and yield strength
of confining steel.
By using Nanovea's Mechanical Tester in indentation mode, using a cylindrical flat tip, yield strength
data can be easily obtained.
Mercury Scientific's static powder flow tester, Evolution Powder Tester, is an economical and easy-to-use instrument that measures the unconfined yield strength
of a material (a critical flow property) at pressures up to 500 KPa.
