EXPERIMENTAL DYNAMIC PLASTIC BEHAVIOR OF SHELL INTERSECTIONS

An experimental study into the dynamic behavior of intersecting hemispherical and cylindrical shells fully clamped around the base of the hemisphere and subjected to a uniformly distributed internal impulsive load is reported. The loads are sufficient to cause plastic flow of the material. The materials used were mild steel, a highly strain rate sensitive material, and Aluminum 6061T6 which is very strain rate insensitive. It was found that above an angle of 45 deg off the base of the hemispheres, the size of the cylinder affected the deflections, though above a certain size cylinder the deflections remained constant. It was also found that aluminum and mild steel results could be meaningfully compared by using the initial strain rates and Cowper Symonds relation.
