A NUMERICAL CODE FOR DETERMINING VELOCITIES OF EXPLOSIVELY ACCELERATED FRAGMENTS FOR ONE-DIMENSIONAL SLAB GEOMETRIES

摘要

This report presents a computer program which determines the asymp¬totic velocities of explosively accelerated flat plates when the geometry is substantially one-dimensional. The computer program makes use of a standard finite difference code to approximate the three conservation equations of one-dimensional fluid dynamics. The computer code utilizes the best available approximation to the equation of state of Composition B and has a 4-parameter equation of state which is suitable for most inert materials. The program is believed to be sufficiently general to handle the majority of one-dimensional problems relevant to the multi-layer fragment warhead program.
