AN EXPERIMENTAL STUDY INTO THE DYNAMIC INELASTIC BEHAVIOR OF SPHERICAL SHELLS AND INTERSECTIONS

An experimental investigation has been conducted into the dynamic inelastic behavior of fully clamped hemispherical shells with and without radially intersecting cylindrical nozzles. The models were subjected to impulsive velocities which were distributed uniformly over the inside surfaces of the shells. Tests were conducted on specimens made from hot rolled mild steel, which is highly strain rate sensitive, and repeated on Aluminum 6061 T6, which is almost strain rate insensitive. It is evident from comparisons with various rigid-plastic predictions that additional theoretical studies are required in this general area.
