According to the fitting results, the significance level values of all variables, P, are less than 0.001, indicating that the regression is extremely significant; the adjusted R 2 values of all variables are above 0.8, and as per general conventions, the closer the R 2 value to 1, the better the fit.
As depicted in Figure 9 b, there has been a clear trend indicating that the flexural capacity of a beam rose in tandem with the augmentation of the area of reinforcements.
On the other hand, due to the behavior presented in the In 600 alloy Au/Pd coated, it is suitable to consider a moderately significant trapping effect (see arrow in Figure 8 ); however, evaluating its second transient was impossible.
With the increase in Bi content, the tensile strength of the Cu-xBi-10Sn alloy shows a decreasing trend; when the Bi content is 3 wt.%, it reaches a maximum value of 331 MPa.
The macroscopic performance is that the test curve shows a decreasing trend with the increasing mass substitution rate of the coal gangue.
Therefore, compared with the control group, the samples with a 15% SS addition showed a decreasing trend in strength, which was consistent with Figure 4 .
As depicted in Figure 5 a, the real part ε ′ of the complex permittivity exhibited a decreasing trend with an increasing frequency of electromagnetic waves.
The results revealed that the addition of glass fiber improved the mechanical properties of the MgO-SiO 2 -H 2 O system; meanwhile, with an increase in fiber content, the mechanical properties showed an initial increase followed by a decreasing trend.
However, this strain maintained its clear relationship with the geometry of the cylindrical specimen, that is, it was associated with the external and internal radii; The normal stress σz at the crack front showed a trend with a positive slope in the central band, a characteristic parameter of cylindrical specimens.
It maintained an increasing trend towards the external radius of the cylindrical specimen; The centroid of the plastic strain presented in the flat area of the crack front was not located in the central part, as in flat specimens.
The centroid showed a clear trend towards the external radius; A clear geometric trend of the plastic strain presented in the flat zone of the crack front was found when evaluating qualitatively with non-normalized thickness parameters under the same load regime; The evolution of the plastic strain’s size in the crack front’s flat area depended largely on the thickness and the load applied for the analysis.
By characterizing the micro-pore structure, it is suggested that with the decrease in open porosity, the compressive strength showed an increasing trend.
Different from the case of specimens with an A orientation, for specimens with an ST orientation and an r/R of 0.1 and 0.2, when the crack is short, f increases with increasing ξ, while in other cases, f shows an increasing trend with increasing ξ.
Figure 7 demonstrates a clear trend, with the higher grade reinforcement exhibiting larger yield drift ratios followed by relatively shorter ultimate strain in the beams and columns.
Calculated specific surface area (S BET ) and pore volume (V BJH ) are summarized in Table 1 , and a significant trend can be observed.
In addition, the onset temperature of melting ( T m ) of the amorphous ribbons shows an increasing trend, and the end temperature of melting ( T l ) does not tends to decrease with increasing x ( Figure 4 b).
Moreover, Figure 4 a shows a decreasing trend of the viscosity with increasing particle size, which has been reported by Liu et al.
Assuming a constant angle of the structural plane, the uniaxial compressive strength and elastic modulus of the sample exhibit a decreasing trend with an increase in water content.
The table shows a clear trend of increasing at.% silver on the surface of the PTFE samples with an increasing sputtering time.
When analysing the fatigue behaviour of cellular structures made of aluminium alloy AA 5083-H111, the effect of rolling direction on the fatigue life may be significant, especially in the high-cycle fatigue (HCF) area.
It can be seen that with the decrease in tube diameter, the condensation HTC in the enhanced tube shows an increasing trend; additionally, the tube diameter has a greater impact on the condensation HTC than the enhanced surface structure.
[ 26 ] conducted experiments on M35 tool steel at −185 °C with different holding times and observed an increasing trend of carbide particle coarsening with increasing holding time.
However, this value is quite close to the level of significance of α = 0.05.
It can be found that with the increase in the axial cutting depth, the range of milling temperature change is small and accompanied by a decreasing trend.
Observing the pore pressure curves in the figure, it can be seen that after starting to heat the test blocks, the pore pressure of all the test blocks at the measurement points showed a trend of first rising and then falling, which is because with the increase in temperature, the free water and chemical water near the measurement points evaporated into water vapor, and the water vapor gradually accumulated in the closed micro-pore structure inside the concrete, resulting in the gradual increase in the pore pressure in the micro-pore structure, and a continuous increase in the pore pressure.
