Abstract:

This paper presents the effect of angle of incidence of the shock front on reflected impulse loading on a finite structure. Impulse reflection factors have been developed for angles of incidence from zero to ninety degrees. Reflected impulse on a finite structure is much less than reflected impulse on an infinite plane because of the unloading due to rarefaction waves propagating from the sides of the structure which lowers the reflected overpressure.
