These stress-strain curves are used for finite element model input data as shown in literature [3].
The comparison of axial stress versus the diameter reduction curve from the FE simulation and the experiment as well as the maximum true axial stress in the center of the specimen can be found in Fig. 2.
The simulated axial stress versus the diameter reduction curve coincides with the experimental one until crack initiation, where the experimental curve drops suddenly.
For the FZ, as the notched round specimen from the FZ is not available, the T0 for the FZ is assumed roughly as three times of the yield stress of the FZ according to literature data [12], which leads to T0=1600 MPa.
Based on the axial stress versus diameter reduction curve of notched round specimens, the cohesive strength T0 is fixed.

The price aspect of construction and the fact that the measures leading to reduction of operating expenses on a facility are more expensive in terms of investment prevail in decision-making process in the Czech Republic.

Flexible General can be regarded as pure friction piles, the resistance of pile tip is zero, the penetration of pile tip is zero, pile tip is equal settlement section, that is, (16) (1) Reduction (16) (17) When r=a, z=0, formula (17) is (18) Vertical force balance by pile body: (19) From Figure 3 you can have the following conditions: (20) (9), (15) substituted (18), combined with (19), (20), can have value. is the position of the neutral point, also the first sink surface.
When other conditions unchanged, based on data over Tianjin-Binhai high-speed (26) calculation, Pile-soil stress ratio increased as the cushion modulus，its relationship as the calculation of the curves in Figure 5, the 3 point in Figure 6 is the measured pile-soil stress ratio when cushion modulus is 30,50,90 MPa.
In the figure, measured and calculated values have some differences, but changing trend, calculated values from (26), (26) with elastic deformation equation multiplied the reduction coefficient to be.
This shows that plastic effect of cushion is obvious, but more complex plastic State, reduction factor value under the influence of many factors, easily lead to errors.
Under Tianjin-Binhai high-speed of data by type (26) calculation known, Pile-soil stress ratio increased as the pile modulus, its relationship as the calculation curve in Figure 6, but changes range of pile-soil stress ratio between 1~4, site test [7] results: Cement-mixing piles under embankment of pile-soil stress ratio between 2~4, both basic anatomists.

The economic effect was obtained through the reduction of rejects, the improvement of the quality of the metal, the abandonment of the costly operation of evacuation (about $ 25 per ton).

The experimental data on the influence of grain size on solid-state weldability in the range of SP have been obtained.
According to the literature data the upper limit of ultimate strain at superplastic forming does not exceed 300% [6] in most cases.
When analyzing the obtained data, one can certify that the processed NS Alloy 718 sheets exhibit sufficient formability for processing various complex shaped hollow parts by SPF.
The data of heat treatment for the NS alloy correspond to the Aerospace Material Specification (AMS) requirements.

Eqs. 1 allows for the correction of the gas yield data, which is presented at room temperature conditions typically, to the decomposition temperature instead [7]. ∅= ∅STP × VcVroom= ∅STP ×TcTroom (1) Where Vroom, Vc, Troom, and Tc refer to gas volume at room, crystallisation, absolute room, and absolute crystallisation temperatures.
MIPAR image analysis software was used for the extraction of transient height change data.
Due to the complexity of the images, colour segmentation tools were found to be the most useful for extracting the data from the image, establishing the white shades in the foam to separate them from the other background colours of the image.
The frames from each experiment were imported into MIPAR to extract the transient sample height data.
An optimal value exists though, as concentrations above 3wt% only produce a small reduction in foam density.

Beside the numerical technique and element formulation, material data and boundary conditions are essential for successful computation.
In order to perform successful numerical simulation, additional material data are required.
Experimental data are necessary for the evaluation of the parameters in this model.
Therefore the data have to be used with sufficient consideration.
Therefore, they have to be determined reasonably by experimental data or reliable references.
