Abstract The problem of longitudinal impact of a thin finite-joined shell, consisting of a cylinder-truncated cone-cylinder, is analyzed both experimentally and analytically. the model analyzed is a 1/100-scale replica of a portion of the Apollo/Saturn V vehicle. Experimental results were obtained from a drop-test system. Longitudinal and circumferential strain pulses were monitored on each section of the joined shell. The velocity of the impacter ring prior to impact was measured and used as a boundary condition in the solution of the governing partial-differential equations. A “bending” theory, including transverse-shear, radial-inertia and rotary-inertia effects, was used to analyze the finite-joined shell. Appropriate transformation relations were developed at each of the joints between the cylinders and truncated cone. The results were then obtained by solving the governing equations numerically by the method of characteristics. Good agreement between analytical and experimental strain profiles was obtained.
