Extract

In a paper published in 1956 the senior author analysed the problem of the creep bending and buckling of a reinforced circular cylindrical shell subjected to the action of a bending moment constant in time and along the axis of the shell. With the aid of the principle of virtual displacements he found that the problem is governed by two simultaneous non-linear first-order differential equations. The equations were integrated step by step with the aid of a desk calculator and satisfactory agreement was found between theory and experiment when the results were compared with experimental data obtained in the laboratory of the Polytechnic Institute of Brooklyn. The experimental investigation and its results were described in ref. 1 as well as in a research memorandum of the National Advisory Committee for Aeronautics and the theory was presented in detail at the Symposium on Structural Problems of High-Speed Flight held at Cranfield, England, in August 1956 and published in the Journal of the Royal Aeronautical Society in 1957.
