Sentence examples for ground specimen from inspiring English sources

Furthermore, it is shown that the propagation in ground specimen is affected, in both environments by the specific crack shape resulting from the initiation process and subsequent coalescence of multiple initiated cracks within the grinding scratches.

The ground specimen displays an almost biaxial compressive stress parallel and near to the specimen surface of 3 GPa, which decreases almost up to zero in a depth of 5 μm.

Approximately 1 mg dry weight per ground specimen was then sub-sampled for continuous-flow isotope ratio mass spectrometry (CF-IRMS) analysis of nitrogen and carbon.

A residual stress of the ground specimens has been measured in the near free surface of the X-ray diffraction.

Nevertheless the cross-sectional SEM study showed signs of nodular corrosion, observed mostly on the ground specimens after long exposure times.

Surface crack initiation was encountered on the ground specimens as well as on the specimens that were hard-turned and subsequently shot peened as a final machining process.

Also, the surface condition of ground specimens and the grinding wheels were evaluated by a metallurgical microscope and by an SEM system after high-speed grinding in order to choose the suitable machining conditions.

The results showed that conducting the WEDM process with the new generation of machines has a detrimental effect at high fatigue cycles, reducing fatigue strength by approximately 10% in comparison with ground specimens.

It was found a degradation of about −35% for the 4-point bending fatigue limit at 2 × 106 cycles of the ground specimens in comparison to the electro-polished ones.

In the present study Retzius lines and prism cross-striations were observed in variably ground specimens after etching with nitric acid of different concentrations (0.1, 1, 2.5 and 5%) and for different time periods (15, 30, 45, 90 and 180 s).

A higher mineral-to-protein ratio than that of bone has been previously reported in deposits from five JDM patients, using FTIR spectroscopy on powders from ground specimens and FTIR imaging [ 8] that was performed on small 2 to 4 μm sections, while we mapped the whole specimens.
