Bifurcation in Tension of Nonlinear Spherical Caps
Publication: Journal of Engineering Mechanics
Volume 109, Issue 1
Abstract
The loss of stability by so‐called bifurcation in tension of geometrically nonlinear plates and spherical caps loaded by axisymmetrical cross forces is examined. These phenomena are manifested by a transition from axisymmetrical forms to the nonsymmetrical ones with formation of wrinkles. They may occur on plates, and also on caps when the loading acts on their inner (concave) side. In these cases, the meridians are stretched at every point. It is necessary to distinguish between these phenomena and bifurcation in compression. The latter is impossible for plates and shallow caps and may occur only on relatively deep caps when the loading acts outside (convex side). Experimental observations of the stability loss by bifurcation in tension are described. Qualitative investigations of the writer indicate, in particular, that the considered phenomena cannot occur when the edge supports are fixed.
