Study of the anti-penetration performance of concrete with different coarse aggregate content. E-mail: qqqwucheng Deep penetration experiments were performed on five types of concrete with different coarse aggregate content. The projectile diameter was The damage laws and damage mechanism of the target were analyzed.
Combustion, Explosion, and Shock Waves. Using these formulas, the ballistic resistance of targets was studied and the possibility of optimizing their structure was shown. The results agree qualitatively with available experimental data. It is found that these velocity values depend weakly on the areal density of the target and are mainly determined by the properties of the substrate material. Unable to display preview.

Penetration depth is a measure of how deep light or any electromagnetic radiation can penetrate into a material. When electromagnetic radiation is incident on the surface of a material, it may be partly reflected from that surface and there will be a field containing energy transmitted into the material. This electromagnetic field interacts with the atoms and electrons inside the material. Depending on the nature of the material, the electromagnetic field might travel very far into the material, or may die out very quickly. For a given material, penetration depth will generally be a function of wavelength.
