Abstract : An experimental investigation was conducted to study the dynamic instability and tripping characteristics of specific stiffened rectangular flat plate design due to hydrostatic and impulsive loading. The air backed test panels were constructed of 6061-T6 aluminum with externally machined longitudinally, wide flanged T or Z stiffezners and were tested under clamped boundary conditions. Test panel loading was provided by a manual hydropump for static testing and by the underwater detonation of an eight pound, cylindrical TNT charge for the dynamic test. The static test panel was instrumented to measure pressure, strain and plate deflection. The dynamic test panel was instrumented to measure transient strains and free-field pressure. The data obtained from these tests was qualitatively analyzed and compared to the results of geometrically similar narrow flanged T stiffened panel results currently available in the literature.
