EFFECT OF SHELL GEOMETRY AND MATERIAL CONSTANTS ON DYNAMIC BUCKLING LOAD OF ELASTIC PERFECT CLAMPED SPHERICAL CAPS

A numerical experiment using the finite element method to show that the nondimensional dynamic buckling pressure of deep elastic isotropic clamped perfect spherical caps subjected to suddenly applied uniform pressure is represented by a function of the geometric parameter and the thickness to radius ratio of caps. Three definitions of geometric parameter are considered. The effects of material properties are also taken to consideration.
