Abstract:
Nowadays, stationary objects exposed to dynamic loads in the form of various impacts are located not only on land but also in water. Therefore, this study is aimed to determine the minimum velocity required for the complete penetration of a supercavitating projectile made of a heavy tungsten-based alloy into underwater protective structures such as spaced steel barriers. The required velocity is calculated using a mathematical model based on the Prandtl-Reuss equations for elastic-perfectly plastic materials. Calculations are performed with barrier thicknesses of 15+5, 15+15, 20+20, 20+30, and 25+35 mm. Theoretical analysis has shown that monolithic barriers are more efficient than equivalent spaced barriers with a distance between plates of 10 mm. The obtained results indicate that an advanced study of this problem is required.
