Abstract:   (973 Views)

One of the important research areas in protection of underground structures is evaluation of projectiles penetration depth in ground as a protective cover. The phenomenon of impact and projectile penetration is dependent on several factors that one of the most important of them is the effect of soil moisture. Therefore, this paper is aimed to study of GBU-28 penetration depth in sandy and clayey soils and effect of groundwater level on penetration depth by means of AUTODYN software. The results have shown that soil moisture plays an important role in projectile penetration depth in different times of explosion. Generally, projectile penetration depth in clayey soil is more than sandy soil with same densities, but increasing rate of projectile penetration depth compared to dry soil in sandy soil is a little more than clayey soil.

Keywords: Soil Moisture, GBU-28, Impact, Parametric Study, AUTODYN.
