内容記述 | Shock wave propagation in polyurethane (PU(R)) foam was experimentally studied. The experiment was conducted in a shock tube by measuring pressure along the PU(R) foam in a shock tube, by means of holographic interferometry and streak camera recording. It was found that the stress-strain curve of PU(R) has an inflection point. When the pressure behind the incident shock wave was below the inflection-point pressure P_c, the wave impedance ratio of the incident shock wave and transmitted pressure wave Z_i/Z_t increased sharply. This indicates that only a small amount of energy is transmitted into the foam if the pressure is below P_c. For pressures larger than P_c, Z_i/Z_t decreases asymptotically to a small finite value. | |||||
