A survey of some buckling problems.

2 3 4 5 i Some results recently ound in the course of current research on several buckling problems are presented and discussed.These problems are (a) initial post-buckling behavior and imperfectionsensitivity of spherical and cylindrical shells under external pressure (b) initial post-buckling behavior and imperfection-sensitivity of toroidal shells under hydrostatic pressure and tension (c) imperfection-sensitivity of axially compressed cylinders with inside or outside stringers (d) buckling of a model structure having a continuous spectrum of random imperfections (e) dynamic buckling of imperfection-sensitive structures and (f) buckling of spherical caps under concentrated loads.
