Abstract
Owing to the existence of the flow field boundary, the shock wave load near the boundary is different from the free field shock wave load. In the present paper, the hull plate load subjected to underwater shock wave is investigated based on wave motion theories; in addition, the experimental study of the hull plate load is carried out. According to the theoretical analysis of the hull plate pressure, we find that the hull plate pressure oscillates repeatedly and decays rapidly with time passing, the maximum hull plate pressure is 2/(1+n) times the maximum free field pressure, where n is the ratio of impedance, and the impulse is much smaller than the free field impulse. Compared with the experimental study, the theoretical results agree well with the experimental data.
