Fuel Tank Survivability for Hydrodynamic Ram Induced by High Velocity Fragments. Part II. Numerical Analyses

Abstract

Numerical finite difference (CRALE) and finite element (NONSAP) calculations of the behavior of fuel tank front panels, penetrated by steel fragments impacting at velocities of 1.0-2.0 km/sec were used to explain the phenomena observed in an accompanying experimental program (Part I of this report). Analytic expressions for the variation of peak pressure and impulse along the panel as functions of fragment size, velocity, and panel areal density were derived from the finite difference runs and used as boundary conditions in the finite element calculations of panel failure and displacements.
