Employing functionally graded materials (FGM) as the core is an appropriate alternative to achieve this goal [3-6].
Yang et al. [11] investigated the effect of different core materials on blast energy absorption of sandwich panels under blast loads, numerically.
Materials The geometry and configuration of the sandwich beams used in this study is shown in Fig 1.
The elastic properties and orientations of the materials were introduced.

In this research, radiography was utilized for identification of a damaged art-historical material.
These results showed that a combination of radiography, image processing techniques and consideration of physical principles of radiation interaction with materials can produce a very clear image which can be used effectively for hte detail analysis of cultural heritages.
Evaluation of material thickness by radiography and measurement of films optical density Radiographic experiments were conducted on a Lorestan antique plates using AA-400 film.

Apparently, this is due to the prospects of the use of such reactions in engineering, especially in developing new materials that are environmentally safer and economically advantageous to the existing materials [1, 2].
This opens the way for the synthesis of substances and materials in nanocrystalline and amorphous states [1, 2].

The reasons are as follows: in the first stage, material distort under the action of biggish tension stress, at the same time, the liquid film between the crystals perhaps separate, but the volume proportion of liquid is bigger and can flow freely, which supply material into the distortion area in time and avoid the fluid film separation.
Besides the hot cracks, a few cracks generate in the course of cooling, this is because the shrinkage quantity led by cooling is bigger than that of deposition layer, which make the residual tension stress in the deposition layer increasing, when the tension stress in local area exceed the material ultimate strength, the cracks generate.
