Equation penetration concrete velocity explosive shape depth factor

Thus, mass loss ratio equation is revised as follows: Unconfined compressive strength of concrete. The projectile can be considered as a rigid body at low velocities. Furthermore, the DOP of the mass loss model unlikely increases as impact velocity increases. The target crater is the initial stage of the whole penetration process, which reflects a considerable part of the penetration ability Liu et al. Hence, the penetration depth curve is calculated as.

Simulation model of impact using finite element analyses on reinforced concrete slab have been proposed by Teng et. It insulates homes from heat loss as well as sound penetration. Furthermore, coatings are placed on the windows to improve efficiency. It is often blown into attics as loose fill cellulose insulation. Thermal conductivity values are numerical values that are determined by experiment. Numerical results indicate the viability of the proposed model of the impact on reinforced concrete to be carried out for impact simulation both for normal and oblique impact of the projectiles. Another variable that affects the rate of conductive heat transfer is the area through which heat is being transferred.

In the factor 1 , the properties of the constituent of concrete such as the materials of which the aggregates are composed, the amount, size and distribution of the aggregate components and the relative volumes of aggregate and water—cement paste should also have a considerable effect on this amount of energy. The function G is given by:. Overall structural responses and failures: What Can Teachers Do
