Abstract
A series of simulated seismic bending tests have been undertaken on pressurized cylinders having diameter-thickness ratios in the range 10 ≤ Dm/t ≤ 28. Ratchetting of the cylinder wall has been observed and recorded in the hoop direction. Finite element analysis which models the experimental set-up and the cylinder material has been undertaken. The results obtained from the finite element work and from a previously available analytical solution both overestimate the experimentally obtained ratchetting rates considerably. The dynamic bending moment necessary to initiate ratchetting is, however, well predicted.
