Many structural metals possess dynamic fracture and fragmentation properties of materials that differ appreciably from their static counterparts.
Analysis of the dynamic behavior of materials, several kinds of tests such as tension, compression or shear may be used.
Lateral efficiency loading can be widely used in the specimen ring on a variety of sizes and materials without limitation.

As the same as metal materials and ceramic materials, polymer materials, One of the most important types of materials and the foundation stone of the modern social life, has been widely used in the current activities of human society one of the most important types of materials.
Compared to general macromolecule materials, some characteristic of the macromolecule material with special properties materials are higher than the general materials.
Through the research of high performance sports equipment, we can promote the development of macromolecule materials science.

Experiments were performed by using an improved test system of physical parameters of rock materials.
In this paper, an improved test system of physical parameters of rock materials was employed to test permeability and porosity of tight rock materials under high temperature and high pressure.
Fig. 1 Schematic diagram of flow chart of experimental facility Experimental Materials and Method The main experimental materials were tight rock and distilled water.
Results show that there are some micro-cracks in the tight rock materials although the experimental model samples of tight rock materials have no macroscopic cracks.

Commonly used adsorbents include natural waste such as carbon-based materials, diatomaceous earth, fly ash, and sawdust.
However, there have been no reports on the oil absorption and regeneration performance of EG oil absorbing materials based on commercial expandable graphite, which is not conducive to the large-scale practical application of EG oil absorbing materials.
Simply put 50 ml of oil materials in a beaker, and then about 0.1 g of EG is weighed and poured into the oil and stirred to stand.
