ELASTIC-PLASTIC RESPONSE OF STRUCTURES TO BLAST AND IMPULSE LOADS

Abstract

The report discusses the general types of failures of typical structures that are used in aircraft and missiles. The theories of elastic and plastic deformation of these structures are presented and comparison with experiments of simple structures is given. It is found that the side on impulse can be used together with rigid-plastic theory of buckled and collapsed cylinders to predict plastic deformation for a wide range of pulse durations. For beam type structures the impulse and rigid plastic approximations seem to only hold for pulses of very short duration.
