文摘
A theoretical model is developed for producing blast loading by rarefaction waves Sudden timed overpressure release yields differential loading on a test specimen The model simulates blast load experiments and analyzes the blast characteristics The model demonstrates possible blast load shapes including negative phase loading The model allows an analytical analysis of the basic parameters of the blast pulses Excellent agreement is achieved between calculated and measured experimental pulses
