Abstract:

This report presents a theoretical foundation, computational procedures, and a computer program for the analyses of bifurcation or collapse of circular, cylindrical panels and rectangular plates. Discretization is accomplished via a variable-spacing, orthogonal, finite-difference grid using the principle of total potential energy. The modified Newton-Raphson iterative procedure is used to generate nonlinear load-deflection curves and a separate branch of the program provides a bifurcation analysis based on linear, prebuckling behavior. The program is capable of handling rectangular cut-out and initial geometric imperfections a variety of zero force and zero displacement boundary conditions and point loads, line loads, and distributed loads in transverse, longitudinal and circumferential directions, as well as axial end-compression.
