Various factors such as grading, grain shape, relative density, grain arrangement, draining conditions, stress path, mean effective stress, and anisotropy affect the behavior of sands.
However, soil anisotropy as one of the crucial factors affecting the behavior of sands is a less-known parameter due to a strong relationship between soil anisotropy and inherent characteristics such as soil fabric. soil fabric interrelates with soil anisotropy in the deposition process, where a grain assembly forges a unique structure regarding the environmental properties and inherent characteristics such as grain shape and size.
These admixtures reduce liquefaction potential by improving mechanical properties in order to incease strength and reduce deformability.

The properties of packed materials are not always included in the technical analysis process of the pneumatic transportation system, especially in the methodology of constructional and technological calculations.
Therefore the material must be additionally affected by vibration in order to release the particle bonding forces, the so-called autohesion and adhesion forces that emerge at the walls of volume; the forces affected by vibration reduce their values to quantities equal to the gravity force of particles that can be described by the relation (1) [7]: (1) where: h – number of contacts of a particle bonding point m – particie mass g – acceleration The analysis of materials that evaluate the practical solutions in such systems has demonstrated that in conveying PM the effectiveness of sucking in suction intake devices depends on the density of the material and approaches zero.
After analysing the manner of mechanical fragmentation of packed materials, it was concluded that the most prospective way to improve the pneumatic transportation process of packed materials is using the energy of compressed air in the suction head in order to fragment packed materials.
Causing pneumatic disintegration that has a direct influence on the physical and mechanical properties of the packed material – thereby improving the physical state of the transported material itself, and suction conditions in the output collecting zone, guarantee the stability of operation of the whole line.
To define optimal parameters and evaluate the effectiveness of the process of pneumatic fragmenting-disintegrating packed bulk materials, one must determine the factors that influence its behavior.

Introduction Electroplating is one of the methods to change the surface properties of the solid materials, such as improving the appearance of the component, increasing the corrosion and abrasion resistances of the materials.
Just for the mechanical products, 70%~80% of the components need electroplating.
Therefore, tests on the electroplating properties are essential parts of the electroplating processing.
When the coating reaches a certain thickness, due to the limitation of the hammer impact load, only the coating will be affected by the impact load, but the substrate metal will not have plastic deformation.
