The advantages of hydroformed parts include the increased strength to weight, weight reduction through more efficient section design, reduction of number of parts and subassemblies, improved quality of formed components in terms of dimensional stability and repeatability and reduced tooling developing costs [3].
The reference status, corresponding to the upper level, is in solid line while the lower level is in dotted line Figure 4: Independent actuators positions on the blankholder profile Anova Analysis The correct analytical approach to evaluate the influence of process parameters on HIMB data is the ANOVA method.

Generally, rollers are used in reduction furnaces with N/H atmospheres with working temperatures up to 1100°C and expected lifetime operation up to 3 years [1].
Investigated Materials Fused silica rollers The roller was in service for approx. 2 years with significant thickness reduction and occurrence of chip offs on the surface.
Fig. 3 Typical microstructure of rollers in as received state (SiO2 content 99.69%) Fig. 4 Typical microstructure of broken roller (SiO2 content 95.45%) Fig. 5 Presence of iron (light spots) at the surface of rolls, mostly in the vicinity of cracks Fig. 6 XRD data of the build-up surface Mechanical properties of roller at macroscale were measured by compression strength.

When the wall studied was perpendicular to the plates added, a reduction of the displacement with respect to the reference model was observed, Fig.6 and Fig.7.
Therefore it can be concluded that the reduction of the displacement in the walls of the tank considered is basically due to the fact that the plates improve the structure bending strength and not to a change in the evolution of the cavity that happens when the plates are parallel to the impact walls.

In order to do the most effective things, experiments should be done to get the accurate data about which fiber should be added and how much to add.
Designers should know the reduction of stiffness may lead to overall and local instability, so there is a practical limit to the thickness of member(such as piers, flange, the girder web), apparently reliable minimum thickness is related to the protective cover, reinforcement configuration and workability of concrete pouring The fire performance of high strength concrete is poor.
But for high- strength materials, elastic deformation of the total share is larger, if ignore the deformation, means made greater reduction of material deformation performance, thus to some extent, affect the application of high-strength concrete, especially the field which have higher requirements for seismic performance of structure.

The time step reduction ratio can be set in order to reach a given precision for the crack initiation criterion at the beginning of the unstable crack extension stage; this precision has to be consistent with the convergence criterion used in the MNA.
Input parameter are given in Table 1, the effective material tenacity is an equivalent value taking into account a reduction of the real material tenacity due to the pressure driven forces on the crack surfaces.

However, the existing external economic relations complicate the purchase and exploitation of these products and lead to equipment downtime and production reduction.
The reduction of laser radiation efficiency was up to 25%.
The sketch of the full-scale sample to control hardness distribution over the hardened surface, measurement zones (1 – 4) The obtained data analysis allows to conclude on hardness distribution ranging between 50 - 60 HRC on the surface.

As it went back to -0.2 V, it could be seen that there were reduction peaks appeared.
As the CV scan was repeated, the polymerization potential shifted toward the lower potential, thus shifting the oxidation and reduction peaks to the more positive potential [12].
Vorrada Loryuenyong contributed to the conceptual approach, analyzed the data, helped in the discussion of results and thoroughly revised the paper.

Introduction
Rapid prototyping technology is the automatic construction/fabrication of physical objects directly from computer aided design (CAD) data sources.
According to [2], in 1994, Pratt & Whitney were able to achieved cost reduction and time savings of 70 to 90 percent by incorporating rapid prototyping into their investment casting process.
Besides the reduction in time, mould-made techniques also requires less skill; therefore, the skills are more easily and effectively learned.
