APPLICATION OF EULERIAN AND LAGRANGIAN COUPLINGS TO ESTIMATE THE INFLUENCE OF SHOCK PRESSURE LOADING ON THE TITANIUM SUBMERSIBLE HULL USING FINITE ELEMENT ANALYSIS

A. Chennakesava Reddy

Abstract :

<p>The aim was to estimate the influence of shock pressure loading on the submersible hull using finite element analysis. The fluid medium was molded based on Tait’s equation of state. The equation of state from Jones–Wilkins–Lee (JWL) was used to describe the detonation products of explosives. The explosion and fluid were interfaced using Eulerian–Eulerian coupling and the fluid and shell were interfaced using arbitrary Lagrangian–Eulerian coupling. The plastic displacement of the submerged hull has been found to be 0.0412 m for explosion charge of 15 kg. The titanium submersible fails at the shock load factor of 0.45 for the explosion charge of 25 kg.</p>
