Excerpts

The incorporation of SSMP resulted in a decreasing trend in material strength at 1 day, with a more pronounced decrease observed with higher content.

It was found that the hardness values, residual stresses, and depth of influence exhibited an increasing trend as the pulse energy was raised.

ANOVA results ( Table 7 ) further confirmed the dominance of target porosity, which yielded a highly significant F-value of 86.66.

The wave velocity of the test blocks showed a trend of first decreasing and then increasing, and then it rapidly increased with an extension of the curing time.

It is further observed that in the sixth hour of the test, it has a decreasing trend, which shows that the coating maintains its integrity, exhibiting only a late minor degradation.

A clear trend of increasing absorbance values is observed with longer deposition times, which is attributed to the increased thickness of the thin films.

Clearly, the YS of the material shows an increasing trend, but the growth is not significant, while TS and EL show a declining trend.

Based on Figure 9 and Table 2 , it was revealed that the compressive strength and flexural strength of the new fast-curing polymer material sand consolidation exhibited an increasing trend with an increase in mesh number under the conditions of 10–15 mesh, 60–80 mesh, and 325 mesh.

The apparent porosity of castables with only added AEA and alumina bubbles after being dried at 110 °C and treated at 1300 °C presented a decreasing trend as CAC content increased.

Also, an increasing trend is observed for the melt pool’s width with the VED.

In the coatings from the other electrodes studied, the same tendency towards a decrease in wear is observed until certain values of pulse energy are reached, which are different for each specific electrode, after which an increasing trend is registered at E = 0.05 J.

The analysis of flexural strength across concrete specimens with varying C/A ratios and cement types, shown in Figure 3 , reveals a clear trend in bending resistance.

Figure 10 shows that with increasing aging time, the fatigue life of modified asphalt exhibited a decreasing trend.

The BET measurements show a clear trend of decreasing specific surface area and pore volume with increasing TEPA loading, which is attributed to physical occupation of pores by TEPA molecules.

[ 7 ] observed an increasing trend towards the use of endocrown restorations and extended onlays that do not rely on a post-core system, instead utilizing a box-shaped preparation to enhance retention of the crowns or onlays.

Stress within the root dentin showed a decreasing trend from stage S1 to stage S5 in most models at both levels.

Consequently, the SLW of the aerosol jet shows a decreasing trend, which is similar to the trend observed when the total gas flow rate changes.

As the number of FTs increases, the bending load-deflection curve shows a decreasing trend, but the peak load reduction is less significant compared to the TS.

It can be observed that with the increase in FTs, the overall ultimate peak deflection in both states exhibits an increasing trend.

According to the ANOVA results in Table 5 , the variation in the water-to-binder ratio had the most significant and highly significant effect on all evaluation indicators throughout the sulfate dry–wet corrosion process.

They found that the mechanical properties of RAC, such as compressive strength and dynamic elastic modulus, also showed a trend of initial increase or stabilization, followed by a decrease over time.

The test results showed that the density of the specimens showed a decreasing trend with the decrease in the interface temperature, but the porosity was always below the 3% threshold specified in the standard.

In contrast, the Cu-excess specimens displayed lower power factors at temperatures below 423 K, but exhibited an increasing trend above 423 K.

With the increase in temperature, the number of hydrogen bonds in each system showed a decreasing trend in general, which was mainly considered to indicate that the molecular thermal motion was intensified after the energy of the system was increased, making it difficult to maintain a stable hydrogen bonding network, and the hydrogen bond energy was low, making it easy to be destabilized at high temperatures.

p -values of responses 1 to 6 were 0.028, 0.01, 0.003, 0.023, 0.002, and 0.026 are less than 0.05, indicating that the model is highly significant [ 86 ].
