As shown in Figure 1b,c, the interlinked ZnO nanosheets were in crooked rather than freely stretched shapes, which indicated that there existed stress in ZnO nanosheets.
However, owing to the sharp discontinuity in the material properties at interfaces between two different layers, there may exist stress concentrations causing severe material failure (Weissenbek et al. 1997).
For such a distinctive regime to exist, stresses associated with mantle convection have to exceed the strength of the rigid lithosphere, which may happen with weakening of the lithosphere.
Mr Williams-Thomas said he was unsure why the trend appeared to exist, stressing it was "a complex issue" that could involve factors such as disparities in the age of sexual consent in the UK compared with other countries and their perception of females.
What international public health programs that did exist, stressed vertical disease programs such as smallpox eradication, malaria control and yaws treatment.
Beside the tensile stresses, there exist bending stresses, torsion stresses and radial pressures from the small length-related radial force of the wires.
The compressive stress in the solder finish is quite low, less than 10 MPa; nevertheless, there exists a stress gradient around the root of a whisker.
The S-N curves indicated that power-function relation exists between stress levels and fatigue life of PC.
In this article, we use FEA to find whether or not there exists a stress singularity at cylinder on flat contact according to different variables, such as applied displacement, coefficient of friction (COF) and fretting wear cycles.
In particular, the LNA predicts that there exists a stress level for which the size of the noise is minimized while, in contrast, the IOS predicts the noise level to increase monotonically with stress.
