Equation penetration concrete velocity explosive shape depth factor



However, several times differences might be obtained when these models are used to predict under some experimental conditions because of the relative singleness of the data that they relied upon. Penetration of grout and concrete targets with ogive-nose steel projectiles. Dimensionless formulae for penetration depth of concrete target impacted by a non-deformable projectile. In this method, the projectile surface elements were first decentralized, as shown in Figure

Mathematical Problems in Engineering

Let us define simple projectile mass loss, which only involves mass abrasion without considering the variation in nose shape coefficients. The damage situations of the targets were then photographed after the test. In addition, many penetrative cracks were observed on the surface of the test targets. Shockey, A. Zhang, S.

Resistance increases as increases; thus, DOP decreases. Penetration resistance is determined by nose shape coefficient and velocity; in different http://medicinanaturale.pro/slut-porn-30/breast-cancer-find-2270.php, these variables elicit different effects. For the condition shown in Very tight pussy 6 athe DOP is 1. The existing models could not reflect the crater depths for projectiles of greater weights or higher velocities, whereas the new model established in this study was reliable.
