Abstract : Experiments to investigate the response of model planes and model brick walls to deflagrative pressure pulses were carried out in the deflagration simulator described in part 1 of this paper. Calculations based on a one-degree-of-freedom oscillator model were compared with the test results. They led to a set of curves in the scaled pressure impulse plane from which isodamage or destruction curves were derived for the specific objects under investigation. These curves differ from the well known P-I-curves for objects under blast load conditions in that the curves for deflagrative loading split up into two branches in the region of small impulse. This is due to the significant underpressure phase of the deflagrative pulse which causes resonance effects in the response of the loaded object. (Author)
