THE DEPENDENCE OF DYNAMIC STRENGTH OF CYLINDRICAL PRESSURE VESSELS ON GEOMETRICAL PARAMETERS
Abstract
Experimental information was obtained by detonating spheres of C4 explosive centrally located in cylindrical containers. Slightly different results would be expected for other explosives. End capping was accomplished by placing the pipe in a vertical position, standing on a steel plate. Another thick steel plate was placed over the open top end of the cylinder and the assembly was loaded down with about 500 lbs of lead. With this system, explosive spheres of different masses were detonated inside the cylinders to determine the maximum amount of explosive that could be contained without rupture, inside various cylinders. Only one shot was fired in each cylinder. The techniques of end capping in this experiment is not critical if the cylinders have a length of 5 or 6 times the inside diameter. The side wall of the cylinder receives the first impulse before the end plates experience any disturbance. High-speed photographs were taken of an expanding aluminum pipe loaded with 12 gms of explosive. The outside diameter was 3 inches and the wall thickness 1/4 inch. The expansion took place in about 50 microsec.
