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 kmsec 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.
