The damage progression was also evaluated using stiffness reduction and hysteresis loop analysis in order to obtain dynamic and secant modulus.
The data acquisition frequency was set to 1 Hz to avoid noise and loss of signal.
After 120000 cycles, the stiffness reductions in both dynamic and secant modulus were about 4-5% at a load level of 70% of ultimate load.
Despite limited data points, the S-N curves generated in this work show that the stress limit is around 80% of the normalized ultimate tensile stress level.

In addition, historic data for formulation and parameters were collected and analyzed.
Historic data revealed that the processing parameters had to be adjusted several times before the desired color was successfully achieved in some cases.
Experimental data were collected as per the design of the experiment.
Variance table or ANOVA table analysis was used to compare and evaluate each parameter for the final data analysis.
Although related graphs for CIE tristimulus data a* were created, only the dE* values are mentioned in this paper.

It was found that, at the early stages of the
scale reduction, the relevant reaction occurs at the oxide/metal interface between chromia and
carbon from the alloy.
Then we characterize the system involved in the scale reduction and we develop a model based on the thermodynamic of the reaction.
This observation is in agreement with the proposition made by Quadakkers [2] who stated that TA is the equilibrium temperature of the chromia reduction by carbon (Eq. (1)).
(T) is extrapolated in the range 850-1000°C from data published in ref. [19] for higher temperatures.
Log(P(CO))=f(1/TA) for Haynes 230® and model alloys - experimental data and theory Conclusion A model is developed to rationalize the variation of the critical temperature for surface oxide removal TA as a function of the CO partial pressure in the gas phase.

This reduction in optical band gap shifts the glass transition to lower values.
The Tg data fits a second order polynomial better than a linear relation.
If only linear relation is fitted to the data dTg/dP value is found to be -7.78oC/kbar.
Hence, the reduction in optical band gap shifts of the glass transition to lower values under high pressure.
This reduction in optical band gap in Ge20Te80 glass under high pressure shifts the glass transition to lower values.

The analysis of numerous data of X-ray
diffractometry, DSC, Raman spectroscopy etc. shows that such glassforming ICS as SiO2, GeO2.
The numerous data having been analyzed in works [3-11] for such glass-formers as S, Se, SiSe2, GeS2, GeSе2, AsSe, H2O, SiO2, GeO2, Р2О5, As2O3, Sb2О3, ТеО2, BeF2, ZnCl2 is evidence of the influence of various PM on glass and glassforming liquid structures and properties.
Glass transition and relaxation of glass On the basis of the data analysis of the x-ray small-angle scattering of glassy SiO2 Poraj-Koshits [15] comes to conclusion, that «in silica liquids fluctuation of density are incarnated in the form of cristobalite-tridimite-quartz-like sections».
According to the mentioned facts and other numerous data analyzed in detail in works [4, 6-11, 16], it is possible to formulate following notion.
At reduction of speed of cooling, the greater number polymorphoids of LTPM in the super-cooled liquid turns into polymorphoids of HTPM.

One possibility is
to use phenomenological laws that accurately fit experimental data.
This type of law guarantees a good correlation with experimental data and also numerical stability.
The blank sheet is modelled with a uniform mesh of solid finite elements with 0 0.05 0.1 0.15 0.2 0.25 0.3 0 20 40 60 80 100 Contact pressure P [MPa] Friction coefficient µµµµ Experimental data µ=A µ=B µ=f (P ) Figure 2 - Experimental data and corresponding evolutional friction law for the friction coefficient. 75x75 elements and two layers in thickness.
The reduction of the friction coefficient conducts to an increase of the material flow (and consequently of draw-in) in the case of the Friction Law simulation.
At the end of the punch stroke both Friction by Zones and Friction Law simulations present a similar distribution of the contact pressure as a result of the reduction of the contact area of the flange.
