AXISYMMETRIC POSTBUCKLING AND NONSYMMETRIC BUCKLING OF A SPHERICAL SHELL COMPRESSED BETWEEN RIGID PLATES

Presents an analysis of the stresses and deflections produced during axisymmetric postbuckling and determines the deformation states at which the shell may buckle into a nonsymmetric shape. The analysis accounts for finite deflections and rotations, but assumes that the material remains linearly elastic throughout the deformation. An experiment shows that both the primary axisymmetric bifurcation point and the secondary nonsymmetric bifurcation point are stable for a shell with R/h approximately equal to 40.
