The initial parameter method, in the form proposed by V. Z. Vlasov, is presented and extended to the case of symmetric bending of cylindrical shells. It is shown that the method can be used efficiently for the solution of shells with and without intermediate supports. The loads applied to the shell can be arbitrarily distributed and discontinuous in the axial direction of the shell. The problem formulation has the distinct advantage that the complete solution contains at most two unknown “initial parameters.” These unknown parameters are determined from the boundary conditions. For shells on many supports the solution contains additional unknowns which can be determined from the support conditions. In any case, the solution consists of solving only two sets of algebraic equations. Tables of influence coefficients and loading functions for some common load cases are given in the paper. Some examples are worked out to illustrate the application of the method of initial parameters.

Axisymmetric Plastic

Axisymmetric plastic buckling of axially compressed cylindrical shells is studied for semi-infinite shells and shells of finite length subject to free-edge boundary conditions. It is shown that the length of the cylinder has a negligible effect on the buckling load. Reductions in buckling stresses from the classical simple-support value are significant, with the amount of reduction dependent on the details of the variation of tangent modulus with stress. Numerical results are presented for cylinders composed of 2024-T4 aluminum and 3003-0 aluminum.

The response of a circular cylindrical shell subjected to a moving ring load with a constant velocity has been examined in detail when both longitudinal and transverse coupling effects are included. It is found that the correction in the bending resonance velocity resulting from the inclusion of longitudinal coupling effects is small. The results of the analysis may be used as influence coefficients to determine, by means of Duhamel integrals, the displacements and stresses produced by varying pressure pulses.
