Wen Kai Xie, a stall vendor at the Golden Mall, takes pride in the uniformity of his Shandong dumplings, the fat, round specimens that are Flushing's mian of the moment, reflecting a recent influx of immigrants from Shandong, a coastal province south of Beijing.
The experimental program included flat and round specimens.
For microstructure investigation, hot-forged round specimens of 6 mm ɸ were also prepared.
In the experimental phase of the study, notched round specimens were fatigue loaded.
The localized deformation zones in round specimens were found to have a diffuse double cone morphology.
Tensile testing of round specimens and Charpy impact testing of single edge notch bend specimens was conducted at different temperatures.
Square specimens and a high number of layers show significantly higher delamination than round specimens and specimens with low number of layers.
Tensile tests on round specimens at different strain-rate levels (high, intermediate and quasi-static) were performed.
Uniaxial fatigue tests with small-scale round specimens before and after performing the ESR process are conducted.
The deformation behaviour of both flat and round specimens of a dynamically strain ageing material was simulated, utilizing constitutive parameters for an Al Mg Si alloy.
As a result, it is recommended to eliminate the option to use square or round specimens in delamination tests and to revise the CLT standard accordingly.
