Since their discovery by Fisher et.al. [7], carbon nanotubes (CNTs) have sparked both fundamental and practical interest.
The manufacturing and mechanical characteristics of the hot-pressing followed by hot-extrusion-created CNTs reinforced Al-based composite were described by Tao Peng et.al. [17] and Kuzumaki et al. [18].
According to Deuis et al. [24], adding aluminum oxide (Al2O3), silicon carbide (SiC), or titanium carbide (TiC) of varying volume fractions to Al alloy MMCs was observed to increase their corrosion resistance.

The micron-TiH2 and micron-Al-V alloy powders were blended using a tumbler mixer.
The morphology of as-received micron-TiH2 and micron-Al-V powder is shown in Fig. 1 (a-b).
SEM images of as-received micron-TiH2 (a), micron-Al-V alloy (b) and milled nano-TiH2 (c) powders.
In order to study the effects of Al-V alloy on densification behaviors for TiH2-Al-V alloy, both micron-TiH2 powder and blended micron-TiH2-Al-V powders were sintered at 1200 ºC for 4 hours and both shrinkage curves are shown in Fig. 6 for comparison.

As demonstrated by Vosough et al. [33], the authors of this work deemed the error to be acceptable because it was less than 15%.
A small depth and pitch led to similar findings in a study by Kitayama et al. [25].
This concurs with the results from the work of Lam et al. [45] and Qiao et al. [46] who used an evolutionary genetic algorithm together with CAE simulations and cycle-averaged cooling analysis, sensitivity analysis (SA) and hybrid SA– Davidon–Fletcher–Powel optimization respectively.

For the uniaxial state the standard PuD-Al used in the automotive industry was applied, for the shear state the ASTM B831-05 was used and for biaxial states the ISO 16842 was exploited.
For the characterization the standard PuD-Al in the automotive industry the parameters of the tensile test according to the automotive standard PuD-Al for aluminum alloys is applied.
Figure 2: Material parameters of the hardenable aluminum alloy AA 6082 according to the standard PuD-Al Considering the behavior of AA6082 under uniaxial tensile load at room temperature, the tensile strength reaches 330 MPa in rolling direction (see Fig. 2).

Hostens, et al. carried out a study of the pressure distribution of the human-seat interface to assess comfort.
They compared the static back and buttocks support pressures between an air-based seat cushion and foam seats (Hostens et al., 2001).
This force represents 69% of the total weigh of the upper torso of the subject (Chow et al., 1978; Todd et al., 1994).
The pressure maximal at interface are comparables into those pressure measured in a similar condition (Dionne et al., 1998; Hobson, 1992; Bader and Hawken, 1986).
