Abstract:
A procedure for finite element analysis of geometrically nonlinear problems, extending over the pre-buckling and initial post-buckling regimes, snap-through buckling, and accounting for initial imperfections, is described. The computation of the nonlinear pre-buckling path is accomplished by direct iterative solution. The bifurcation point is established by interpolation of solution points of the pre-buckling and immediate post-buckling analyses. A static perturbation method is then developed for determination of the post-buckling path of the bifurcating structure or the limit point of a structure with initial imperfections. Three numerical examples, involving an arch, flat plate and shallow shell, are presented in illustration of the procedure and in comparison with alternative approaches.
