Abstract : The stresses and displacements are determined experimentally in a long circular cylindrical shell reinforced at its midlength by a single uniform ring. Acting at the ends of a diameter of the ring are two self-equilibrating outward radial forces. The experimental results are compared to analytical results previously obtained using the Donnell shell differential equations. Good agreement is observed between theory and experiment for both the displacements and the stresses. The theory predicts and the experiments corroborate that the maximum displacement of the cylinder does not occur under the ring. Both theory and experiment also reveal that the eccentricity between the ring median radius and the shell radius has a first order effect on the stresses in and displacements of the shell. (Author)
