Pneumatic pulsator is a device used in industry storing bulk and loose materials.
Introduction Storage and transport of bulk materials play a key role in many industries.
Literature in particular concerns the phenomena occurring in silos during storage of loose materials.
During storage in silos, loose and comminuted materials attract and retain moisture.

At the same time, some questions exist in the bonding of the automobiles and airplanes, such as dissimilar materials bonding, difference thickness materials bonding.
The bonding of dissimilar materials or difference thickness materials is an importance research project.
Cold pressure welding, not only difference thickness materials and dissimilar materials are thought, but also work environment is thought, can realize weight loss and energy conservation.
Figure 1 shows the initial position of two sheet materials.

That includes anisotropic material behaviour.
The x- and y-directions should coincide with the material axes of orthotropy.
Material variants IV and V differ in plane strain to equibiaxial stress ratio.
