Note that the model has been validated using data obtained from industry.
A CF value of 2 for example will indicate that the blade’s creep life increases two fold from its reference operating condition while a CF of 0.7 will indicate a 30% reduction.
Due to confidentiality reasons, the engine data and configuration will not be given.
Not only that the magnitude of the impact weight is the highest, the logarithmic term indicates that the reduction in the blade’s creep life is accelerating.

For Al alloys many of the required data have been determined in the framework of the European research programme COST 507 [14].
One of the most sophisticated data bases available - including the 15 most common elements of wrought Al alloys (Al-Mn-Fe-Si-Mg-Cu-Cr-Ti-B-Ce-Ni-V-Zn-Zr) and capable of handling quaternary phases like α-Al15(Fe,Mn)3Si - is distributed commercially by ThermoTech [15].
(9) Note that the required microchemistry data, including the particle density entering in the Zener-drag pZ (Eq. 7) as well as the concentration of solids css (Eqs. 3, 4, 9), can be provided by the microchemistry model ClaNG.
The microchemistry data necessary as an input for the softening module AlSoft were computed with the microchemistry model ClaNG.
Obviously, the resulting recrystallization kinetics data agree qualitatively well with the above findings that coiling temperatures in excess of 300°C are required to enable full recrystallization during self-annealing of the coiled hot strip, see Fig. 2.

This methodology compares experimental data with the numerically obtained results.
Therefore, an effective parameter identification strategy based on stress-strain input data should be considered.
The experimental data used in this type of optimization problem is composed by discrete values representing a set of stress-strain measured points, as depicted in Fig. 2.
In addition, the stress-strain numerical results are defined through a curve and interpolations for each experimental point are performed to compare both data.
The hydraulic bulge test results and the experimental (reference) data are in excellent agreement for polar displacements smaller than 35 mm, with a deviation for larger displacements.

The descriptors used for vertical infill panels is the apparent sound reduction index: insulation for airborne noise between different units.
Internal partitions must be characterized by a minimum value of apparent sound reduction index, variable as a function of the intended use of the property.
The apparent sound reduction index has to take into account the sound reduction index of the partition and interactions with the connected structural elements.
A weight reduction between 30% and 60%, which implies lower seismic forces.

Y/T ratio), ductility and toughness, were analyzed based on a large amount of tension coupon test data reported in the available literature.
Besides, a large amount of tension coupon test data and research advances for high strength steels were arranged, the material property features were researched, and the stress-strain relationship model used for the finite element analysis was proposed.
Material Property of High Strength Structural Steels Based on a large number of tension coupon test data, the material property of high strength structural steels is researched from four aspects, including the stress-strain curves, Y/T ratio, ductility and toughness.
Fig. 2 Relationship between Y/T ratio and steel strength [26] Langenberg [5] overviewed the material property of 4 kinds of European structural steels from a large amount of tensile test data, including S355, S460, S690 and S890 steels, shown in Fig. 3.
Fig. 5 Toughness test data of 4 kinds of European steels Based on Fig. 5, it can be found that the transition temperatures of high strength structural steels are lower than those of ordinary strength steels (S355), which means that the toughness of high strength steels is better.
