DYNAMIC PLASTIC BEHAVIOR OF INTERSECTING SHELLS

An experimental study into the dynamic behavior of intersecting spherical and cylindrical shells fully clamped around the base of the sphere and subjected to uniformly distributed loads is reported. The loads were sufficient to cause plastic flow of the materials. The material used for all tests was 6061-T6 aluminum. Due to the limited number of tests conducted on the sphere-cylindrical nozzle intersections, it is not possible to draw any concrete conclusions as to the influence of the intersection. However, it is felt that the nozzle has the effect of reducing the maximum deflection that might be obtained for a spherical cap subjected to the same impulsive load.
